Now there is error labels and this one takes the cake

This was so good I just had to share it.

While checking out E-Bay tonight I found this listing

item number: 320783861177

I wrote the seller and asked:

the certification on the slab says 1950, the date on the coin says 1959

whats up ?

His response was this:

this coin was slabbed by PCI as a 1950 (an error on their part). Such an occurrence is rare and makes it more collectable and more valuable. The 1959 is valuable in it's own right, but in this slab, commands a premium price.
