My comment was refered to who i quoted, but to answer your questions some people think it's stupid but other such as myself that are big glock enthusiast think different!
Honestly Gen 1 Glocks are extremely rare and those that want it are willing to pay whatever it's worth to them which is going to be BIG money. I think a gen 1 G17 could go for easily $800+ as a G19 gen 1 would be over $1000+ easily. If i had one for me everything has a price and i would sell it for $1500 if someone wanted to buy from me. Hell maybe more, at the end of the day people will grow into them and realize it's something that started history and as the years go by the prices will rise more and more!
