Need Help Iding The Date Seated Quarter

1859 is my guess as well.

Whichever slot is empty in your album.

A picture of the reverse would be helpful to see if there is a mint mark. The motto wasn't added until 1866.

We can tell the date isn't from the 1838 to 1849 simply because we can see 185-x

We can eliminate:

1850, 1851, 1856, 1857 and 1858, 1859 because the final digit doesn't look like a 0, 1, 6, 7 or 8

1852 because it has a distinctive upper ball knob

1853 with arrows, 1854 and 1855 are out because the coin in question doesn't have arrowheads at the date


Two dates are left:

1853 no arrows and 1859.

I'm leaning towards 1859 as it has the higher mintage and most, but certainly not all, of the "old weight" silver was melted and re-coined.


Of course, I could be wrong and it wouldn't be the first time nor the last.

Good analysis, MV. Most unlikely to be the tough 1953 No Arrows, so 1859 seems most likely.

From the crossbar on the "5" I'm thinking 1859. This is based only on looking at photos just now - I know little to nothing about Seated Lib coins.
