im not sure why there is a peice of paper with the cert # 26180690
with that coin, im thinking if it is #26180690, it would still be in the
cert slab, and have docs for the auction with it, look see if more docs
maybe he was planning to have it graded and auctioned, an was just
checking stuff out
still a really nice coin, as suggested get it professionally graded & slabbed
