With all my due respect I believe this is still ambiguous.
It looks like you could have a catch-22 situation.
In your last post you explained that you had the seller's coins in your control and could still
release them to the buyer despite him opposing to do so. Yes you can!
But coming back to the my first post, how do you really know that the BUYER isn't the one conniving,
he has nothing to loose in trying, a scanned photoshopped deposit slip and a business card are not a barrier to a con artist.
(The con artist can walk in any branch and obtain a blank slip and a business card and that's all he needs to subsequently photoshop it tranquilly at his home and send it to you).

Both parties stand firm to their version.
How are you going to verify?


Thank you.
