[QUOTE="lkeigwin, post: 1273609, member: 30400"]I don't know of any dip or brightener that doesn't have an unworldly effect on red copper. It is usually easy to spot and the TPG's are ruthless about BB'ing them. While I am certain that there are many coins in TPG holders with a red designation that are no longer red, and also understand why NGC and PCGS will no longer guarantee copper color forever (copper is pretty unstable), there is no question that there are numerous original red coins that are many, many decades old. Shoot, an OBW roll from the 1960's or earlier is commonly filled with bright red cents looking as fresh as the day they were minted. It all comes down to how coins are stored. As for the OP's question about turning a dark brown coin milk chocolate color, certainly it can be done. Many large cents has been recolored, not necessarily to make them mint red but for other eye-appealing reasons. I wouldn't recommend it. Lance.[/QUOTE]
