Would I pay that for those? No.
Does that mean he's crazy for asking that? Might not be.
Most in this thread are judging the price compared to the actual firearms. That is not what these are. They are their own market. A diehard Glock collector might see that price as worth it.
First off, it's only worth that sort of money to someone who wants something Glock that you cannot just go to the store and buy.
Second, I remember when Hockey cards and Comic books used to be worth a lot of money. I had more than a few of each that were worth a couple hundred at one time.
Third, I can say the same thing as most here about half the guns we can buy. Tavors, RFB, Swiss Arms, etc. They are all extremely over priced yet most in this thread own some. Then there are these "Anniversary" fancy edition guns like Colt's 1911 that are double the price of what a normal 1911 sells for. Yet people just keep buying them.
