Oldest/Rarest Coin Before & After Restoration

[BetterThanTexas]

It might be interesting to see some coins people found, their story, where, depth, & Material (medium) they were found in. Or whatever you would like to share. Before & After would be best. After is fine if it has already been restored. The process used in restoration would also be helpful. If Electrolysis was used. Off The Shelf cleaning or home made recipes were used. Or any coin for that matter that you felt like restoring.
