Specimen is about 20cm x 16cm and varies up to 4cm thick. Consist of mainly native silver with tiny wires, sheaths,herringbone etc. Some calcite on one side but most has been etched out. Do not know the exact location but came from a well known dealer about 6 years ago. Would like to know its value at todays silver prices. Weight is about 60 troy ounces. Thanks for your help. More photos or questions if needed.
Well silver is currently trading for around $33US/oz. Silver from Cobalt area is typically 95% silver but can be as low as 85%. Assuming 20% of the 60 oz. is due to inclusions of cobalt arsenides etc. that leaves 48 oz of silver. Assuming it is 95% silver that leaves about 45 oz. of silver at $33/oz which gives you about $1500. If you clean it you will likely get more for it possibly as much as $3000 if you do a good job of cleaning it.
