CoinPrepby The CoinHQ

For coin, medal and token sellers

The $40 coin shouldn’t take $40 worth of your time.

Upload the batch of photos from your photo table. CoinPrep removes the backgrounds, organizes each item, identifies what you photographed, researches the pieces that need it, and drafts your listings. You review everything before anything leaves the tool.

You do the numismatics. CoinPrep does the desk work.

Cleaned, organized and named automatically.

CoinPrep suggests a descriptive filename from the piece it identifies, then numbers every photograph of that same item for you. No more renamingIMG_4821.jpgby hand.

The piece shown is a 1907 McKinley memorial dedication medal from our own stock, as photographed and as the tool returned it. Nothing is retouched after the cut. It came back named:

1907-mckinley-memorial-dedication-medal-1.jpg

Some inventory is not difficult to sell. It’s difficult to find the time to list.

The $40 medal should not take $40 worth of your time.

Built for raw coins, medals and tokens.

Whatever is on the table comes back the same way: a worn cent, an irregular medal with a suspension hole, a token nobody has catalogued. The background goes and the piece stays exactly as you photographed it.

One sitting. One set.

A dime and a dollar fill the same frame. Same size, same framing, same background, every time, so a grid of your listings reads as a catalog, not a camera roll. White, black or transparent, chosen on the way out.

How it works

  1. Step 1

    Upload the batch of photos

    Drag in a folder straight off the phone or camera. JPG, PNG, WEBP and HEIC, any size, up to six shots per piece.

  2. Step 2

    Every piece is cut out and framed

    The background goes. The coin stays exactly as you photographed it. If a rim got clipped or the shot was cut off at the edge, that one is flagged so you can take a look. A crooked coin gets straightened, in two-degree steps.

  3. Step 3

    Group, identify, name and export

    Tick the shots of one piece. Press Identify and it reads the photographs: series, date, mint mark, metal, a descriptive grade, a title and a description ready to edit, and it suggests the filename the images should carry. Press Attribute and it searches for the catalog reference and the published size. Press Deep Research and it also looks for comparable sales. Download a ZIP of named, numbered images with a CSV, one row per item.

One piece, all the way through.

1959 Oregon Centennial Beaver Dollar HK-573 North Clackamas County Uncirculated
Condition
Uncirculated. Bright golden oreide surfaces with mint bloom intact; the beaver, the lettering and the raised outer band show no wear, and the piece appears uncirculated. Scattered small dark specks and carbon-like flecks are visible in the obverse center field around the beaver and, more lightly, in the reverse center. A few very small rim nicks and a shallow scuff show along the edge, most noticeable at the lower left of the obverse as photographed. No holing, mounting evidence or plating traces are apparent in these images.

  • The arc of initials above the beaver is not fully legible here; the original coin reads K.M.T.A.W.R.G.S. for the company's eight members, so confirm the die matches before transcribing it in the listing.

Description
Issued for Oregon's statehood centennial by the North Clackamas County Chamber of Commerce, which sold the pieces at 50 cents to defray the cost of centennial events in the county. It is cataloged as HK-573 in Hibler and Kappen's standard work on so-called dollars, the term for dollar-sized commemorative medals of this kind; 20,000 were struck in oreide, a gold-colored brass alloy, at a standard 38 millimeters. Both sides copy the 1849 Oregon Exchange Company "Beaver" ten dollar piece, gold coined privately at Oregon City before the federal mint reached the Pacific Northwest. The obverse center shows the beaver on a log with an arc of initials above, T.O. and the date 1849 below, and small stars and sprigs in the field, ringed by AN EXACT REPLICA OF THE HISTORIC "BEAVER" TEN DOLLAR GOLD PIECE and, outside the border, A SOUVENIR FROM MIRACULOUS NORTH CLACKAMAS COUNTY. The reverse center reads 10. D. 20 G. / NATIVE / GOLD. / TEN. D. within OREGON EXCHANGE COMPANY, encircled by OREGON CENTENNIAL 1859-1959 between two stars. The gold-colored surfaces retain their original bloom with no wear; scattered dark flecks show in the fields and a few tiny nicks are present on the rim.

Sandwich Bank M.B. Castle Sandwich Illinois Civil War Store Card Token Copper
Condition
Extremely Fine. All of the lettering on both sides is complete and sharp, with only light rub on the highest points of the letters and the beaded border, and the beading is visible around most of both rims. The surfaces are granular rather than smooth, with scattered dark specks and small pits, and there is a darker area at the upper right of the reverse and shallow roughness through the reverse center. The copper is a bright orange-red that does not look like undisturbed original surface, so the piece may have been cleaned or brightened at some point; no holes, edge bumps or mounting evidence are visible in these photographs.
Catalog reference

  • Examine the initial before "B. CASTLE" under magnification: sources split between M.B. Castle (the banker Miles Beach Castle) and W.B. Castle, and the reading may decide the Fuld die/merchant listing.
  • Confirm the exact Fuld number against the printed reference before advertising one: market listings for this copper bank card are usually cited as IL 775A-1a (R-5), while at least one cites a 775A-2a (R-3).

Description
A Civil War store card — a privately struck, cent-sized token that a merchant or bank put out during 1862-1864, when federal cents had vanished from circulation — issued for the Sandwich Bank of Sandwich, Illinois. The bank was opened in 1856 by Miles Beach Castle (1826-1900), a New York native who came to DeKalb County, ran a lumber business, published the Sandwich Argus and later served in the Illinois Senate; the bank continued under his family and became the Sandwich State Bank in 1919. The obverse reads SANDWICH / BANK / M.B. CASTLE / SANDWICH, with small ornaments and ILLINOIS curved along the lower rim inside a beaded border. The reverse reads DEPOSIT / EXCHANGE / & (flanked by ornaments) / LOAN / OFFICE. The piece carries no date; cards of this kind were struck about 1863. It is copper, and the published size for the issue is 19 mm. Sandwich, Illinois pieces are cataloged in Fuld's store card reference, but published descriptions and grading-service labels differ over whether the initial before B. CASTLE reads M or W, so no catalog number is stated here. Lettering is sharp with light rub; the surfaces are granular, with dark specks and a bright copper color suggesting an old cleaning.

Why I built CoinPrep

I built CoinPrep because I dreaded the desk work that came with buying a new collection.

Photographing the pieces was easy. Then came opening every image in Photoshop, cropping and rotating it, removing the background, resizing it, saving it with a useful filename, working out exactly what the item was, searching for references and comparable sales, writing the description, pricing it, and finally creating the listing.

That work was especially hard to justify on lower-value coins, medals and tokens. I might buy a group of 50 new pieces, each with a likely selling price of $10 to $100, then spend days photographing, identifying, researching, pricing and preparing listings for all of them.

Some inventory is not difficult to sell. It’s difficult to find the time to list.

So I built the tool I wanted for my own inventory. CoinPrep takes a batch of raw photographs, cleans and organizes them, suggests and applies meaningful filenames, identifies each item, researches the pieces that need more work, helps estimate a selling price when reliable market information is available, and drafts the listings for me to review.

It has saved me an enormous amount of time, particularly on the pieces I used to keep putting aside because I simply did not have time to list them.

I am still the numismatist. CoinPrep handles the desk work.

Built for a numismatist, not a stock photographer

Your coin, untouched

Most background removers redraw the coin to get rid of the table, and the lettering shifts, the toning changes, a worn rim comes back sharp. This one only removes what is around the coin. What you photographed is what the buyer sees.

It tells you when to look

Every cut-out is checked. A clipped rim, a shot that ran off the edge of the photo, a piece that came back too small: those get a flag on the card. Nothing is thrown away for you; you look, and you decide.

You pay for what you use

Two credits cut out a coin, up to six photographs of it. One more identifies it and writes the listing. Five looks it up online. Eight goes deep. Nothing is spent until you press the button.

Simple pricing

Start with 20 credits free, no card, and 20 more every month. Two credits cut out one item, up to six photographs of it. One more identifies it and writes the listing. Pick the plan that matches how much you list.
