Quote: Finally, where's the best place to go for up-to-date pricing for paper bills and whether or not there are current/adverse conditions affecting their existing values?
I'm not sure what the second question in this sentence is asking...
As John1 mentioned, condition dictates value on just about every collectible...baseball cards, coins, paper money, postcards, bottles, road maps, lunchboxes etc. Modern star notes included. If something is rare or scarce the condition is less of a factor. It's a supply & demand thing.
