I saw this lot of Fake Peace Dollars today: You can see the auction here: https://www.ebay.com/itm/365893295375 The seller even shows the individual coins on a scale where the coins are under weight. I'm trying to draw attention to this to help others.
Looking at them, I don't really see any indications of them being counterfeit. Then again, by no means an expert on the subject. Where I do see a concern is the weights of 24 grams when they should be 26.7, clearly out of tolerance even for wear.
