I Definitely Understand The Fun In Collecting Notes

Hey guys-
I'm very new to collecting (coins and notes) in general. I sort of fell into it when I was left a decent sized coin collection by an uncle of mine who died.

I really like the coins themselves. I love the weight and the fact that most of them contain 'real' valuable metal.

I had a friend who strictly collected paper currency. I always remember thinking 'who would pay 100 dollars for a piece of paper worth only 5?'

But now I understand it all. There's is so much history and Americana contained in the artwork of our paper currency.

Yesterday I purchased my fist gold certificate note, and added that to a small collection of 2 dollar bills, silver certificates and one confederate note.

Though I can't say I'm happy that my uncle died, I am happy that he had the foresight to know that collecting various forms of currency is something I would love doing.

So with that, I ask.
What do your note collections contain?
Like I said I have a very small collection of silver and gold certificates and a couple odds and ends.

Thanks for all the great info this forum has given me so far!
