Hello, Keven --

Yes, the dates on Buffalo nickels were located in such a place that they were among the first features of the obverse to wear down. A dateless Buffalo nickel is no less a neat find, especially if you happen upon it in regular pocket change (only about 1 in every 25,000 nickels in circulation is a Buffalo nickel). However, dateless Buffalo nickels are worth only about 25 cents each.

Happy collecting!
Josh
