Thanks, I used the macro setting on my camera and held them over a lamp.
I noticed that about Ebay prices too.
I'm cleaning them today with a rag lightly dampened with water and another rag with a tiny amount of olive oil. They were on a chain so I'm temporarily restringing them with knot spacers and rolling a paper tube to hang/store them in a darkened place until I figure out what I want to do with them.
