The coins are sealed in a plastic holder and a plastic cover but the backside of the plastic cover developed a milky film that isn’t removable as you can see from the 2nd picture. Comes from a smoke free home. The set includes the following. 5 Yuan (KM #537). 10 Yuan (KM #538). 50 Yuan 17.1 grams, 32mm, silver. 100 Yuan 221.1 grams, 35mm, silver. I would be happy to answer any questions or provide additional pictures if needed.
