Your signature of "J. King" caught my eye.
The man that got me interested in coins was "V.J. King".

Years and years ago I had a commercial coin dipping product that I occasionally used. That was probably when Reagan was President. Now I fully understand all the reasons not to dip, but are any commercial products now available that anyone has used? I see some doing a google search but who knows what they are composed of . . .

Jeweluster and E-Z-Est are the most prevalent commercial dips, they are composed of thiourea and sulfuric acid.

There was a coin ( Seated half dime w/ arrows) I was interested in purchasing last week with a $50 price tag. It had some toning which I didn't mind except a small portion of the rim was turning black. I asked the dealer out of the Half Dime & a toned Barber quarter which of the 2 he thought was a better deal (same price). He replied the Half Dime & insisted I could get a better Barber quarter if I waited. I mentioned I had some reservations due to the smidge of black on the rim. He said "gimme a second" and came back with the same coin blast white. I thought it was a diffrent coin but he told me he just dipped it.

Yes, the black was gone (although the beautiful rainbow patina was too). The luster was non-existent & so was my interest.

I noted something left out of this string - probably because it is obvious to all the experts who replied: While a warm water rinse after a dip is fine, IN ALL CASES the chemical dip should be neutralized (a solution of baking soda is common). That solution needs to be rinsed off completely. Professionals use deionized water for all treatments. The less fortunate among us should use distilled water. A dip in acetone will help the coin dry faster with a hot air blower or compressed air (with a good filter).
