It looks like a pretty good deal, I just wish I could afford it at the moment. A little outside of my budget right now.
MCM runs specials from time to time. Sometimes they sell out with a certain allotted quantity within a few hours.
Now, if we can just get them to do that with rolls of Libertads, it will be a very good day. Don't worry about a scam; Modern Coin Mart is a primo operation.
I've purchased from MCM many times and have always been satisfied. They run some great deals on eBay quite often. Good company and excellent customer service.
