The second coin is a silver dollar. It is 90% silver and minted at Philadelphia. The coins, plastic holders, original packaging and certification are all in perfect condition with2 exceptions. In picture 4 in the white fabric on the lid you can see impressions from the coins. They were not in their indentations on the bottom and left a depression on the top. I believe this is temporary and will push out over time. The second is in the seventh picture. On the far left of the certificate about half way from the top there is a small reddish brown stain. Not the end of the world but in the spirit of full disclosure you're now aware of it! These will be professionally packed, sent insured and a signature will be required at delivery.
