I can certainly make the dies. 4140 is relatively easy to machine if you know how, and it will harden "hard enough" for a low production number of from a few hundred to a couple thousand coins. I also keep a bit of O1 and W1 on hand for those cutting tools I can't hand grind from HSS or carbide. I even have a propane forge in the back along with a toaster oven for tempering (although it gets used more for powder coating). I started writing with two questions in mind. Where to buy/make coin blanks at the best price? Not the 10-20 on Ebay or Amazon, but a couple hundred to a couple thousand at a more reasonable bulk price. I forgot the other question, so my second question is what question (or questions) did I forget to ask? Maybe what alloy would best? I suspect an annealed copper alloy of some kind. Many an amusement facility used to have a machine that would take your penny (and a dollar) and roll your penny into a souvenir key tag back in the days when pennies were still copper. -- Bob La Londe CNC Molds N Stuff -- This email has been checked for viruses by AVG antivirus software. www.avg.com
