2foxy Valued Member United States 150 Posts	Posted 03/02/2023 3:56 pm I found this very colorful 1954 S Proof Lincoln Wheat penny in fairly good shape, what might have caused this toning? It doesn't look like it happened naturally, does this negatively affect numismatic value? Thanks in advance :) Report this Post to the Staff

nfine Pillar of the Community United States 3468 Posts	Posted 03/02/2023 4:23 pm Improper storage is another option. By the way, that is not a proof cent. Proof coins prior to 1965 were struck at the Philidelphia mint and would not include a mint mark. Edited by nfine 03/02/2023 4:25 pm Report this Post to the Staff

ijn1944 Bedrock of the Community United States 19146 Posts	Posted 03/02/2023 9:02 pm Yes, not a proof. The toning is the result of exposure to environmental agents--possibly staining. No added value, but if you like it, keep it! Report this Post to the Staff
