Are there telltale signs of a Morgan being dipped- like super shiny for a 100+ year old piece of metal? Supposedly, you cannot tell when it is done correctly. Stains (as in your example) and/or stripped luster are typical from improper dipping. I do know from experience that dipping a copper cent will turn it Pepto pink.  |

This particular coin doesn't look dipped to me based on the photos provided but anything's possible. Dipped coins don't usually display cartwheel luster like this example does; the dip chemically removes a thin layer of surface metal - a layer which is responsible for the appearance of mint luster - and the resulting dipped luster is what I call "all-over" - the coin is sometimes unnaturally bright and the luster tends to "bloom" instead of cartwheeling. If it's overdipped, it ends up chalky and dull/dead looking. In the case of Morgan dollars, some staining was actually caused by storage, particularly a reaction between the chemicals and dyes used in the fabric Treasury vault bags and the atmosphere and humidity in which they were stored. Additionally, handling during post-mint sorting left deposits of oils and dirt on the surfaces of the finished coins that resulted in staining and discoloration after prolonged exposure to air. This should not be confused with the Peace dollars which were rinsed with an anti-tarnishing agent after being minted and prior to being stored, a rinse which often led to white "milk spotting" on the coins.

In this case, I am inclined to defer to paralyse's opinion.  |

Here is a dipped Morgan if you're interested: came back Unc details from PCGS. I dipped it myself to remove a nasty haze. I didn't think it would straight grade but it was worth a shot. VAM 42A. The scratches are from heavy die polishing, not PMD.

Not sure where I come down here. I've dipped (or seen dipped by pros) hundreds of coins over the years without any lessening of the cartwheel luster to the naked eye. Many of the old-time national dealers continued to dip well into the TPG area and seemed to transition to slabs quite easily. I well remember a conversation 25 years ago with a well-known SLQ dealer who attributed such spotting to poor rinsing techniques. |

I can stand by what I said earlier. If done correctly, you cannot tell. I do not say that from personal experience with the process, but based on examples provided here or by coin dealers making the claim. An interesting discussion nonetheless. YMMV.  |

It's not always detectable. As Coinfrog noted, there are dipped coins out there where you cannot easily tell. Was this coin dipped?

Wait - you're asking if the SLQ was dipped?  Edited by Coinfrog

Yup. Do you think it was dipped?

Do I think the 1917 quarter was dipped? Really?

It was, in fact, dipped. When I first got it, it was very dark, almost black in some areas.

Well I congratulate you then. Can you tell us what solution it was dipped in and for how long. Thanks.

E-Z-Est, probably 10 seconds.
Proves your point that you cannot always tell a dipped coin!

Peace dollars are commonly milk-spotted from planchet issues. It is less commonly seen on Morgans but this is a good example.
