Tri-Five Chevy guys, need a hand with hubcaps

[awp101]

We found these in my Grandparent's garage while going through my Grandfather's stuff last year. I know they had a '56 Chevy at one time that he traded in on a '67 Bel-Air somewhere between '68-'70. I also know he wasn't the type to swap wheels and hubcaps to get something cooler or replace them just because they got some road damage so I don't know where, when or why he got them or why he kept them after the car was gone.

I think they're original but are there any markings I should look for? I've seen cherry ones listed for $100/ea but with these being less than pristine, do they have any value? Would they be worth listing on ebay or somesuch?

Don't know about value, but think twice before you clean them. Sometimes its best to leave them in the condition that you found them.
