[QUOTE="Brett_in_Sacto, post: 2289456, member: 71510"]So as some of you may know, I've been collecting Peace Dollars for a while, and learning a lot over the last few years. This year I embarked on building an NGC registry set (I'm 3 away from complete!) and I'm learning a lot about the mints and how the presses worked, and a lot of the details of why certain coins are the way they are. The question I'm unable to answer is this... Specifically for Peace Dollars, but I guess it would be similar for most coins minted around the same era. What happened before and after the press? I'm trying to understand a bit more about toning, "blast white" surfaces and what happens to these things as they age. We start with a blank planchet, do they get any sort of chemical or grease treatment? I have heard that HCI (Hydrocloric Acid) was used, but I'm not sure at what stage. After it's minted, do they go straight into a bag? Did they go to a reviewing table? A chemical bath? Ok, thanks for reading - and now the GTG!!!! I got this over the weekend at a local show. Actually I haven't got it in hand, I pick it up Wednesday night. But I've got the deal sealed and I'm STOKED! It's my Christmas present to me!
