lol If I had gold I could buy all the chocolate I wanted:lol:
A single gold eagle (the current ones, with a nominal face value of $50) is worth something in the region of $1,250. Trying to pay for a bag of M&Ms with what's essentially a $1,250 coin is a real drag. If you ever thought cashiers got grumpy at people who paid for $2 worth of stuff with a $50 bill you ain't seen nothin' yet....
If you really want to push gold coins further try this one:

It's a 100kg coin with a nominal face value of C$1,000,000 and a gold melt value of a little under US$42,000,000
They do a 10kg version as well, presumably for the more budget conscious investor who has a mere $4,200,000 to invest.
