Welcome. Always looking for more Buffalo collectors. If you get a chance, please post photos of the reverses. Although a bit difficult to see, these look like nice examples of late date Buffalos. You have a couple from 1937 and those may include a Three Legged version from Denver.
Regardless, enjoy your nickels. I am biased but believe the
Buffalo nickel is the finest of all series to collect. It has numerous easier dates to accumulate, some moderate ones and some very challenging (for instance the 1926-S and 1918-S in higher grades, the 1913-S Type II and 1914-D in any grade).
