Re: Comex Acceptable Bars and Hallmarks
 

Interesting! I see that Acadamey is not listed, even though they make 100 ounce bars. They also make 1 ounce rounds (A Mark) which are sold by Tulving.

Re: Comex Acceptable Bars and Hallmarks
 

Where do you get "Acadamey" ???

On A-marks website I couldn't find any references : http://www.amark.com/about/#history

Also, they make 10-oz. bars & 1-oz. bars (since 1981).

Re: Comex Acceptable Bars and Hallmarks
 

These Comex approved makers are involved primarily in producing the 1000 (thousand) ounce bars rather than the smaller investor bars, ingots, or rounds. Some of the listed names are not even in business anymore, but their bars are still Comex approved for settlement.
