JM is one of the oldest and largest PM assayers in the US and deals with all kinds of PMs. They have probably seen every form of PMs and assay mark that&#039;s out there. If they are able to disclose the name or source of that bar&#039;s manufacture or provenance, then they&#039;d be the officials I&#039;d place an inquiry with.[/QUOTE]</p><p><br /></p>
