Look on the bright side. At least you know these are the real McCoy. Forgeries do not develop these spots. I think in the future coins with milk spots will be worth more
well if spotted coins worth more in future won't the forgers fake milk spots too? A friend of mine sent me this photo... Perth Mint Shark silver coin swimming in milky sea (Correction: Saltwater Crocodile) :|
Wow that's the worst milk spotting on crocs I've seen yet. You should try rubbing it off with an eraser. Works wonders, especially for croc coins because they're not completely shiny. It'll get rid of the mild spots, and the frosted surface will hide any flaws from the eraser. https://www.youtube.com/watch?v=qgyfi8TnadQ
