looking at buying some bullion coins from the Perth Mint. Two reasons why I wouldn't:
1. You have to provide photo ID before you are allowed to buy, and they check your address against a database.
2. The Mint's cut is ridiculous. If you buy 1/10 ounce coins, you are paying about $1800 per ounce. 1/2 ounce cast bars are about $1500. if you ever had to sell back, then you get hit a second time and they undercut you relative to the average market price. Simply not worth it!
