Geepers ..... another great coin .....
A few comments before bed-time (work calls tomorrow) .... Fun facts as follows ......
This is one of the great USA coins designed by
Laura Fraser .... her husband also being a famous USA coin designer (
Buffalo nickel and others). You can have great fun researching both of their prolific careers in USA coin history.
This is the first USA coin to exhibit the image of a living person .... 1920 Alabama Governor Thomas E. Kilby. This alone is a great coin trivia question answer.
You read my comments on the 2*2 (star) variety in your Missouri thread ...... so I won't repeat them here in detail ..... the only goal was separating the collectors of the time from their hard earned money.
This coin has an unusual compendium of confusing dates ..... follow me here on this logic ....
The 100th anniversary of Alabama Statehood was 1919 ..... the coin was authorized by Congress in 1920 ..... and was finally struck at the Philadelphia mint in late 1921 .... a full 2 years after the Centennial celebrations had ended.
So the coin has three 'official' dates on it .... 1819, 1919 and 1921 ...... this was very confusing to the consumer at the time.
Imagine that happening today?

To this coin .... another beautiful and well struck example IMHO.
The clue to strike weakness on this coin is the eagle front (left) leg and neck ..... and by your photo these are fully struck up.
Some concern about the reverse rim at 7:00 ..... is that damage?
Great coin ..... I see no reason why this could not earn a scary technical grade from a
TPG ..... MS-66 is not of of the question IMHO.
This is a very valuable coin today ..... take care to preserve what your grandmother left you ..... and let us know what eventually becomes of your efforts to understand the coins and history.
