Hello Nathan,
Silver Strikes selling on eBay are the best bargains in .999 Silver. What prices are reasonable depends if you are collecting or melting them down.
Common strikes are normally selling slightly above Melt Value(approx. $18 each) which is why many smelters are selling their brass rings.
Collector Values are suggested between $22-$28 by Bill Cohenour's Guide.
Feel free to contact me for my inventory of commons at low suggested price delivered. Insurance extra.
Thank you,
Gene
