I hate it. I think the fact that the 2013 proof set DOES NOT have the dollar/two dollar coin with the security features in it is telling. I think they are an embarassment, and the so-called savings come at a massive cost to private businesses who have to retrofit all their change machines/parking meters/vending machines.
They are ugly steel slugs, they look fake, they feel fake, and they will never have any numismatic value. NEVER.
