J&M collectors - any information on this 1/2 ounce piece?

First time I've seen this one before - 1/2 oz Temagamai Ontario 1985 Grey Owl Country which just sold for a whopping $184! I am not the new owner. I was watching a similar 1 oz piece that was taken down early on Ebay this week.

Any information on these pieces?

I've never run across one, but with only 200 minted, they are scarce and obviously not to popular when issued.
