Help with Mameita Gin 0

[Pyrolizard]

I picked up these Mameita Gin at an estate auction a while ago and now somebody is wanting to buy them off me, but I have no idea what a fair price would be. I think the smallest is Tenpo era and the middle is Genbun era, but I could be wrong and have no idea about the largest.  Does anybody have an idea of when they're from and what they might be worth?

I've never seen these, let alone be able to authenticate or attribute them. Sorry.....

I was told by my collecting buddy that the first one is worth about $270~$360. If the second one is from Genbun then it's about $90 but if it's from Bunsei, it's worth about $180. He said he can't figure out from the images.  The last one is about $45 according to his opinion.

Oh wow.  I'd never have guessed they were worth so much.  Thank you for your friend's opinion, I appreciate it a lot.
