The 1996 100Y 1oz Gold Panda 15th Anniversary is a very low mintage coin within the Gold Panda series. The official mintage total is only 3,800 coins. Given the widespread melting of gold pandas in the 1990's, the surviving population could be much smaller.
Two varieties of this coin have been identified. I do not know if these are correlated with different mints or die lots, so if anyone knows, please let me know. The difference lies in the position of the 1996 date. One of the dates of oddly off-center under the temple.
It is not yet known which of these is more rare, but the very existence of two clear varieties make the 1996 15th a potential long term candidate as a scarce panda superstar.
