I have no idea if he still makes them. I dug through my old emails and finally found him; his website is https://jwmemorabilia.com/. I don't see Mustang coins on his site but I suppose you could ask if he still makes them.
Anybody here remember the Team Mustang coins that were sold on this forum by a member several years ago? I've got a couple that I will be selling in the Marketplace and I wanted to give credit to the member who made these coins before I post them up for sale.
Not too sure on that; I seem to recall previous discussions when these wheels first came out and it was supposedly around 26-28 pounds per wheel. Might want to ask Need4SpeedMotors.
