Hi, I'm a 67 and a retiree with a rediscovery of my childhood coin collection. First, hello to everyone--I hope to be a regular contributor. Second, I have been buying coins from Esty and eBay and have a question on dipped coins...as in, how do you tell when a coin has been dipped.

Now I know you are probably going to say that if it's shiny it's been dipped but I have coins (silver) from the 50's and 60's that look every bit as shinny as when I bought them.

Now the problem is, if this is a problem, is that I have been trying to buy the best coins I can reasonably afford. Now in terms of quality, I've been looking at the back of the coin to see how it compares to the examples on the internet. Now the problem I'm facing is that the closer I buy to uncirculated the shinner the coins seem to be.

From the sparse reading that I've done, the older the coins are the crustier they are. So am I to assume that everything that I've bought has been dipped...I've got BU from 1916 up to 1945 and you need sunglasses to look at the lot.

Thanks in advance,

Peter

to CCF. First tip is: stop buying coins on etsy!
Second tip: Buy slabbed coins from PCGS,NGC,ANACS
Third tip: learn grading https://www.PCGS.com/photograde

You have to make a distinction between shininess and luster. The problem with overdipped silver coins is that while they can look bright and shiny, they can lose their original mint luster. On the other hand, undipped uncirculated coins can range from heavily toned to blast white, but they will retain their mint luster. It sometimes can be hard to tell from Internet photos, but usually easy to tell looking at coins in hand.

Dip is a mild acid. It removes some of the metal. That can leave a bright surface behind, even with a little mint lustre.

Dip it again and there's almost nothing left. Dip it a 3rd time and it's flat.

Improperly neutralize the acid and it will silently sit there eating away at the coin's surface anytime there's a little moisture in the air... turned in the holder is that term.
