I'll buy at least 10 off of you for spot assuming these bars are .999 fine silver, I'll buy all 20 if you'd be interested in knocking a small percentage off. No need for paperwork as I'll get them tested myself.
I'm EU, so I'm assuming this is preferable for you?
Escrow is no problem, though I'd prefer to do a direct trade. As you can see by my trust I'm not going to run off with your silver.
I will instruct the escrow holder to release payment when the bars have been received and tested to be pure silver. If they test as fake
(no offense meant- you have a low post count) then I'll return them to you and leave appropriate trust feedback.
PM me if you're interested
