We have acquired a large number of Peace and Friendship medals. I can easily tell the very old bronzed copper versions, but it is more difficult to distinguish the later restrikes in the 19th/early 20th and the 1950-70 restrikes. One difference I note on many of the medals is the finer detailed medals uniformly weigh less than the less finely detailed strikes. Sometimes the difference is as much as 30-40g. Are the 1950-70's strikes heavier than the late 19th/early 20th strikes? Thanks for the help.
Welcome to the fun Kelly. I think you will find that anything is possible and nothing is for sure. Many different types of metal have been used to make medals over the years. The ones with the most details came from soft material and or they were made with better presses and dies. Some medals are struck more than once to bring out the details and I believe that took more skill from the maker. Feel free to post images if possible. Folks here love images.
