As long as we understand the quantities of the stuff already dug up, we should re-visit the copper rarity. As far as a rare coin in collectable condition (not dug up, good color, xf+) goes, the rarity is untouched. Can go by Ilyin, etc. There is an influx of common coins in collectable condition and rotten rarities. Despite of the new law, reportedly, all diggers are still digging. Thus, if you include rotten coins into rarity tables, then the rarity is diluted severely. I cannot think of any copper coin (except patterns) that was not dug up in recent years. Even 1762 denga made its appearance 5 years ago on MiM. Albeit, rotten as hell. But, when it comes to regular coins in spectacular condition, and rare coins in collectable/spectacular condition -- there is no supply... They are much harder to get than ever before (IMXO).
