I bought this collection about 50 years ago in New Jersey from a reliable coin dealer. I think that they were collected in the middle or early 20th century. On some of them you can see numbers added by the original collector. Unfortunately I did not get a list of what they were. Most of them have authentic wear and toning. A few have no wear. I suspect that many of them are Ching Dynasty and perhaps older. My wife can read Chinese and tried to help me see what they said.
