What are your thoughts regarding the Perth Mint 5oz High Relief Silver Coin strikes of the Wedge Tailed Eagles, Kooks, Koalas etc? They appear to be rather over priced ~$450 - 500 but hot damn they are impressive looking coins. Doesnt look like the secondary market really values them. I see quite a few going on ebay in the same price range (meaning they are likely selling at a loss after fees right..). I like them so much I might set a goal to acquire one for personal enjoyment, but curious if anyone has had any success in flipping them? or did you get burned?
