First purchased tetradrachm - now what?

I live by the missisippi river in the Deep South, where summer temps regularly get in the mid to high 90’s. Even indoors it still sometimes feels gunkey.

Learning how to spot and treat BD is an important part of collecting ancients. As others have said, the best thing to do is to learn how to spot it and avoid those coins. However, like many (most? All?) of us here, at some point you’ll end up with a BD coin.


I’ve had success using sodium sesqicarbonate. If you search the archives at CT, you should find some good information on this method. I have this site bookmarked, http://www.classicalcoins.com/bronze_disease.html I’m sure there are other sites, including some from CT members that have excellent instructions as well.


I would send this coin back for a refund, especially if you bought it from someone who regularly sells ancients. IMO, a good dealer should not sell a coin with BD unless they fully disclose the problem. However, depending on your coin budget, learning how to cure BD on a $25 coin isn’t the worst thing. At some point, it would be a great learning experience to practice removing BD on some cheap coins
