SILVER DOLLAR REFERENCE GUIDE
1921 Morgan dollar mintmarks: compare Philadelphia, D, and S coins
The original 1921 Morgan dollar came from Philadelphia (no mintmark), Denver (D), and San Francisco (S). On each, inspect the reverse below the wreath and above DOLLAR. A dark spot or soft photograph is not enough to identify a letter; compare a clear close-up of the actual coin before using a date-and-mint price.

These are photographs of individual Store listings, labeled by the seller-recorded mint. Their small web previews are useful for locating the area to inspect, but are not independent proof of a D, S, or absent letter. Open the item and request a sharper reverse close-up if the mark is unclear. Photos and listing availability may change.
How to identify the three original 1921 Morgan dollars
| Issue | What to see below the wreath | Original mintage | Common buying mistake |
|---|---|---|---|
| 1921 Philadelphia | No letter | 44,690,000 | Treating no mark as a missing-mintmark error |
| 1921-D Denver | Small D | 20,345,000 | Calling a shallow D absent without a sharp close-up |
| 1921-S San Francisco | Small S | 21,695,000 | Pricing a raw coin from an exceptional certified sale |
Begin with a full reverse, then enlarge one small area
First confirm you have a Morgan dollar: Liberty wears a cap on the dated face and an eagle sits inside a wreath on the other. On that reverse, find the gap between the wreath and the word DOLLAR. The mintmark, if present, sits there. Check the full reverse before zooming so you do not confuse a leaf, scratch, or spot for a letter.
The three listing photographs above show where to look on real coins. They are deliberately shown as examples of the inspection task, not as mintmark authentication. A strong identification needs an evenly lit, in-focus close-up of the actual reverse with the surrounding wreath and lettering still visible.
What no mark, D, and S actually mean
No letter is the normal Philadelphia issue. A D means Denver and an S means San Francisco. NGC records original 1921 mintages of 44,690,000 Philadelphia, 20,345,000 Denver, and 21,695,000 San Francisco. These numbers measure production, not current survival or the grade of a particular coin.
Denver struck Morgan dollars only in 1921. PCGS notes that its D can be tiny or shallow. If a reverse photo looks blank where a listing says D, ask for a clearer image before concluding the seller is wrong. An original 1921 Morgan with O or CC would be an impossible date-and-mint pairing; modern 2021 commemoratives are different coins.
Compare the letter shape without inventing one
Use a genuine issue reference for the claimed mint and view the actual coin at a second lighting angle. The D should resolve as a letter, not simply a dark oval. The S should have a visible curved shape. Blurry edges, reflections, corrosion, or a mark near the right location can imitate either. If the image cannot resolve the mark, record the mint as unverified for your buying decision.
A mintmark can also be altered or added. If the asking price depends on a variety or unusually high grade, a close-up alone may still be insufficient; compare diagnostics with a recognized specialist or grading service. Do not scratch or polish the area to make a letter easier to see.
Compare price after the mint is established
Find several recent completed sales for the same 1921 mint and similar wear, luster, marks, and cleaning status. Separate raw coins from certified coins. A highest-grade auction record or a price-guide figure for Mint State does not establish what a raw circulated example should sell for.
Include shipping and the seller’s return terms in the comparison. A lower asking price can become a poorer purchase if the photos conceal the mintmark or surface. The common 1921 issues also contain 90% silver, so compare any collector premium with the current silver-content reference rather than a stale metal price.
Five photos that make a useful listing
Ask for the complete obverse and reverse, an in-focus reverse mintmark close-up, an edge view, and an angled surface view. Those pictures establish the date, orient the mintmark, show the rim and edge, and give a better chance of spotting heavy cleaning or distracting damage. Ask the seller for a written condition observation tied to the exact coin.
If the letter, wear, or surface remains uncertain, use a less specific valuation range or pass. A truthful “cannot verify from these photos” is more useful than a confident guess based on the listing title.
