Some of the medals look like they have notches on them, but this is just an illusion caused by the protector (see last image). The medals are all in mint condition. They weigh 1.25 troy oz each, total weight would be around 122.5 troy oz. They are sterling silver, which is 92.5% silver weight. I do not have any paper work or booklet.
