Greenspan on gold

This is kind of hard to listen to but worth it. He says that gold is half commodity and half currency.

See http://www.zerohedge.com/news/2014-11-07/greenspans-stunning-admission-gold-currency-no-fiat-currency-including-dollar-can-ma .  There is a transcript there but it isn't complete.

So in some ways gold acts just like copper or other commodities, like pork bellies or soybeans.  But in other ways it acts like the dollar or euro. Makes sense.  It would be an interesting paper for an economist to write.
