I saw these on Ebay, maybe you guys are interested:

280985674445,
hurry, it ends up in one day or so.
The price seems good to me 80€ for 98 keys but I already have some pick locks and have no idea what to do with them, I saw some of these type of “keys” have huge price tags on some sites, can someone tell me why is that? Do people still use them to open old locks or are they just collectible objects? The seller says they are from 19th century.
I am curious to know more about the pick lock keys, because I have some huge ones and I wonder if they worth anything. What is the thing that makes some of these wanted, the bit, or the age, or just the idea that they are for lock picking?
PS: I am not affiliated with the seller in any way, buy at your own risk! I sometimes see what looks like a good deal here and there and if for some reason I don’t want them myself, I’ll pass them on to you guys, I hope that is ok.
