What is good about these kind of real-life shitcoins?
They are, for what is worth actual numismats. It means, that thanks to history, time and meaning their value will not drop. (ROM)
Is it an investment? Yes it is, although super-long term. There is a big chance that around 100 years from now you(your descendants)will be able to significantly profit from them.

Big problem, IMO, with coins like yours are shipping costs. You are offering those costs "for free" and that's very nice, but i don't collect shipping costs.
Those are "kiloware" coins and numismatic value is equal to zero.
No one will be able to profit from them in 1000 years or more. And if there is any value, it's only locally based.
Imagine why this dude won't ship international:

Good luck with your sales.
