Metal, specifically kilo bars and $100 bags of junk silver coins. Buying/selling at APMEX is easy. Note the buy price.

The bag of coins is 71.5 oz and the premium is only about .75/oz.

I'm not really worried about the 'spread' anyway, as I probably won't be selling this silver until it's well over $50/oz.
I sold some silver bars at just over $40 a few weeks ago. I bought 'em in 2009 under $20.
I'll probably load up on GDX calls tomorrow as the crooks at COMEX/CME work the price of gold down for options expiration.
