It appears to be the Mongolia 2007 500 Togrog Mongolian Wolverine 1 Oz Silver. Sales on Ebay appear to be $152 and up for the few sold listings. There's a nice MS70 PCGS example for sale and they are asking $1995.00 or best offer. A few more for sale in the $900-1100 range.
Wowsers! A coin that was giving to me along with a couple others. I won on Collectors Universe. Thanks JWP!
I'd weigh it and measure it carefully to make sure it has the right weight and size and compare it with pictures of known examples online.

I would watch what type of objects you get too close to the coin. Don't want to add any damage. Then measure to the closest 1/16th or 1/32nd and then go on google and use a conversion calculator.
