1921 p Seated Liberty Quarter Dollar, VG,
a Key Date to the series, this is the only year minted of the series where the last digit is a one (1), so it must be a 1921.
Please note this year is notorious for wear of the date field, the date is very worn on most of the 1921 ebay listings for this quarter.
If you desire a full, 4-digit 1921 then you will need to pay much more than the price of this coin.
Please do your own research, as always.
I am not a coin grader, so you should judge the condition yourself. Securely packaged and handled with care. Sorry No International Shipping, U.S. only.
