so several months back I got a few peace dollars off ebay for a good price, couldnt tell by the pictures they had toning. im positive its artifical, and since they werent key dates and I didnt care, I didnt make a fuss about it, they were for the silver and the coin themselves. what do yall think about it, attraction or deterrent? dont care? im not sure what to think. 2 are rainbow toned and a third is blue...
