The Long Island commemorative was minted at the height of the 1930s commemorative craze. There were 100,053 pieces minted. Though they were fairly well distributed at the original issue price of $1 per coin, there were also numerous hoards of several hundred to several thousand pieces that continued to surface through the 1940s, 1950s, and 1960s. As one might suspect, today the Long Island is one of the more readily available silver commemoratives.
Most Long Islands are mint state, with the average grade being MS63 to MS65. Superb Gem MS66 examples are not difficult to obtain. But MS67 examples are definitely rare. This is probably due to the fact that both the obverse and reverse designs are somewhat flat and marks and abraisions are fairly common. Most Long Islands have frosty luster.
