So today at work a customer gave me a gold coin. It had a picture of " Martin Van Buren"

I looked at it, and looked at the reverse and had a picture of Statue of Liberty and $1 on it.

So I accepted it. I gave it to another customer later that day, but I was totally unaware that new gold colored dollar coins were in circulation.
I looked it up and found this:

So basically they printing old coins for every US President in order.
Including the Presidents who already are on coins.
They even changed the model for Presidents who already have a coin
look at Andrew Jackson

he has a superman curl !!

So sometime soon President Obama, Bush, Clinton, Bush, and Carter will be able to see themselves in a coin. That's pretty cool to be alive to see yourself in a coin.
just fyi
