Would people consider these a double investment, one being a metal and two being collectable? For instance a 1oz Gold dragon.
Depends how much you pay for it. If you got it at bullion price then you got a good deal. There is also GST on proof gold coins. I think just the plain 1oz Gold Dragon Bullion coins has the double investment potential rather than the 1oz proofs. The 1oz proof costs too much at $3100 each. If you are in it for the long term it should pay off though.
