http://www.ebay.com/itm/Buffalo-Sta...em3a8f7934c0Anyone 'in the know' on #500 knows there are two plate numbers... 10208 and 10209...
Stamp is *clearly* 499 in all respects...

And... an "alleged" 500 certed by PSE...

If this PSE certed stamp is a 500, I will renew
my belief in the Easter Bunny & Santa Claus...
These really ice my cake...
Please feel free to chime in...
