It's all a matter of degree. If an uncirc. coin is dipped to the point that the surfaces look chalky, it might not grade. if to the point where the luster is thinned out so the frost is diminished, it will grade lower. Circulated examples will usually grade if just dipped and not harshly cleaned, but will typically be net graded lower than the details might suggest
They do , all the time as long as it was done properly. I have even had PCGS call me & ask if they could do it for me on a bulk package of coins I sent them.
I'm looking at buying a Lincoln cent that was graded 62 BN but the thing is blazing red and at least a 64
Who's it from? Red coins tone over time anyways, and i learned from a fellow member (doug) on here not too long ago, that TPG's offer limited guarantee's on color copper coins. I.E. NGC will only guaranty the price of a RD (red) coin for 10 years, PCGS doesn't offer one at all. So if it is graded BN, get it for a BN price, but keep the red coin bud! Buy the coin not the holder...
Do TPG's grade dipped coins? All the time. Or do they get "Genuine"? Generally only if they are "overdipped", i.e. the coin is robbed of luster and appears "flat". Can they even tell if a coin has been dipped, if done properly? Not 100%, but they can generally take a very educated guess. In general, TPGs are not opposed to dipping, if done correctly. They are much more strict about copper (i.e. they generally won't grade dipped copper), but gold and silver and nickel coins are fair game. Also, dipping is more accepted with mint state and proof coins rather than circulated examples. Hope this helps...Mike
I'd say most "untoned" silver coins have been dipped at least one in their lives. TPGs certify them daily. As long as they were dipped properly and not too many times, everything should be copacetic.
