Only about 3,000 survivors are estimated, with roughly 250 in Uncirculated grades and just about 50 known Full Head -- rarer overall than the 1916 in Mint State.

Other dates and varieties in this series
What to check before you pay, specific to this date.
The same date runs from about $1,997 worn to $34,451 at the top of the scale — a 17× spread. Nearly all of that gap is condition, not the date on the coin, so work out where an example sits on the table above before deciding whether its asking price is fair.
Every figure on this page depends on that S. The same year from another mint is a far more common coin, which is exactly why added and altered mint marks are the usual way this date gets faked. Ask for a close-up of the mark itself — a listing title claiming it is not evidence.
A PCGS or NGC holder settles authenticity and grade in one go, which is most of what you're actually paying for at this level. The premium it adds is small next to the cost of being wrong about either.
Every Standing Liberty Quarter listed here is priced by an individual seller, so the same coin in the same grade can differ by a wide margin on any given day. Sort by price, check Metal Points and order history for a sense of the seller's record, and message them if the photos don't show enough to grade confidently.
