Archie, They are still worth more to a collector than to someone like me. They have approximately. .6 of an ounce of silver in them. At today's price that would make them have about $11 worth of silver. I myself would send them to a refiner along with 1000+ more ounces and would in return receive about 90% of the value of the silver back. The 10% covers the cost of refining the silver along with getting a true assay. Making my return on a silver strike about $9.90 per. Obviously I don't and can't do this for free. So I would pay something back of the $9.90 depending on how many you had. Hope this all makes sense. Let me know if you need any more info.
