But none of them appear to be valid. Any other parts of the address that might be not fully readable?
I found some old picture files on my computer
@cyptomania can't you just simply post the image or the relevant part of the image? (Of course, work with a copy, keep the original safe).
Of course, if the image also has private key info you'll have to hide that or cut it out.
I mean that if you share the image of the address (without other info) no harm is done and some extra pairs of eyes may be able to help.
PS. I hope that you are aware you'll also need the private key if you want to spend those coins.
