so today I visited my grandmothers house. I happened to know that she had a fairly usable cube in one of her drawers, so I got it out and began to clean up the internals. my grandmother noticed this, and suggested I look in another drawer and see if there was a cube in there. there was an original '80s rubik's brand 3x3 and another cube I could not identify inside. Having looked at these I reached farther into the drawer and pulled out two original McDonalds promotional cubes, complete with boxes. I was very excited with this discovery even though the cubes didn't turn all that well. my Grandmother let me keep a mcdonalds cube, so I wanted to ask if this cube was worth anything. is it?

the stickers have a bit of wear, and the cube has some manufacturing defects. I might be able to get some better pictures if you need them.

It's priceless because it was given to you by your grandmother.

if you want a sellable price, look at an auction site. You'll find plenty.
