I can’t speak to the silver, as I am a total nincompoop as to how silver oxidation works. As for the bronze copper, I know for a fact that the cupric-oxide leaches everywhere. In fact, this is a metal detectorist’s bane. When I take my metal detector and swing over a bronze target, what I’m actually getting a reading on is the green copper “halo” from all of the years in the ground. It skews the identification of signals. Sometimes stomping on the ground will disturb the signal enough that I can get a better read on what the item is. If you get an example of multiple metal-type coins in a target, digging usually results in finding that the cupric oxide bonds to whatever copper is also included in that target. All silver coins have at least a small amount of copper in them, so you are going to get a little bit of greening. in a way, the greening is a sign of authenticity.

A Report from the NWCC spring coin show. March 22-24th, 2024 The Northwest Coin Club’s spring money show was held in Brooklyn Center Minnesota this weekend. It is one of the larger coin shows in the United States. The dealer floor was packed wall-to-wall with people. I’ve never seen so many smiling numismatists in one place in my entire life. There were roughly 100 vendors in attendance. Out of those vendors, only 5 were selling ancients of any kind. There were no pick bins or bargain boxes to be seen anywhere. Most of the identifiable coins were not of the best quality, and few were suffering from early stage or late stage terminal bronze disease. I got lucky and found a Probus while hunting thru a flip box. It’s a nice strike on a clipped planchet. As a side note, I was awestruck at how many junior coin collectors were in attendance. Kids with parents, Scouts, and some very serious-looking high schoolers with Whitman folders and IPads roamed the show floor. Be nice to them, for they are our future and will buy our estate collections some day. There will be another show in the fall.

Showed up for the coins. Signed up because of this thread.
