We are taught never to touch our coins with our bare hands. I have seen many dealers pick up coins with their bare hands. I had my eye on a certain coin my local dealer had. I took three very nice Morgans in flip holders to him for trade. He seemed interested. He got out his felt board and laid it on the counter. Then he took the Morgans out of the flips with his bare fingers, held them in his hand to examine them with his loupe, then put them on the felt. He then took the coin I wanted out of the flip with his bare fingers and laid it on the felt. After all that he declined my offer and picked up all the coins with his bare fingers and put them back in their slips. When I asked him about that he said he knew what he was doing. I have seen other dealers handling coins with their bare hands.
What's up with that? I thought dealers would handle coins the right way. A few years ago I bought a Maple Leaf from another dealer. He had a tube full of them. He poured them into his bare hand and told me to choose. He then took the one I wanted with his bare fingers and picked it out for me. Needless to say there were fingerprints on the coin that never came off,
