Website For Lincoln Penny Values

You could also try copper coins which I like because it gives you an approximate value based on grade of coin . But notice I used the word approximate. Good luck

Valuations on errors and varieties are notoriously difficult to find.

Lots of say cents are in the market, sold, and so it's (relatively) easy to figure out prices for say a 1953 Lincoln Cent in AU55 Red/Brown.

Die chips are generally no additional value except for a few with PR departments (BIE).
Small Cuds and die breaks the same.

There is a generic error price guide at Mint Error News, but it covers only a few (off-centers).

There is the same problem for varieties - the few major ones that the TPGs identify are listed in most price guides (1955 Doubled Die, 3-legged Buffalo, etc.).

But the smaller ones ... it's whatever a buyer and seller agree upon. Take my pet series, 3 cent silvers. In a year where the mint made 5 million coins using around 120 dies, and one of them has a repunched date... it's not crazy rare, but it's not common either... is it worth the same as the regular coin? 10% more? 20% more?
