This afternoon I received a 1891 Indian Head Cent I purchased off eBay. Super nice coin which I'll post in a few days when I get a chance to photograph it. But, in the USPS box with the coin was a 1972 hardbound edition of the Blue Book. I did not buy this nor was their any indication from the seller that this went with the purchase. So, I sent him a note about it and offered to send it back if he wants it back. Weird. Never had a Blue Book in my life.
Congratulations on that purchase. I’d leave great feedback on him but I wouldn’t mention the book. Everyone will expect something extra. A very nice seller.
