How to get a fair market price for small amounts of physical precious metals?
A user rightly commented on this question to say product recommendations are off topic. As I thought it was an interesting question I edited out the product recommendation, and the edit was approved.
Since then it's been closed as off topic. Could someone please have another look at the question and suggest which part of it might still be considered to be off topic and maybe recommend what further editing would be needed to fix it?
