I have old foreign post cards dating back to the 1800's I also have other post cards from the us as well I want to know what there worth

Hi, bonnie11!

That would depend on at least a few things like, who the manufacturer of the card was, the subject on the image of the card, the overall condition of the card and also what someone would be willing to pay for them.

If you would provide some additional details, that would be helpful. We don't guarantee results, but we can try!

Thanks!
