Is it a 10c, 25c or a 50c? Ok a 25c Not listed in the Breen book or in the Cherrypicker's book. Not a QT. May be a 10c or 50c. In that condition 10c = retail $6.00 ws $3.50; 50c = retail $18.00 ws $11.00 None made in QT. Todays silver melt $3.8249 if not more than melt, I would buy, if reasonable, to keep and see, if it is a new variety, for later.
if its lower than $25, KEEP IT!!! It will be worth it! in my opinions, I think it might be a 1910 over a 1916 or 1918.
