Currency Pricing Guides?

I think you would be better off with a piece of paper noting what you want. Here is a link for paper money values,click on Values and then download the PDF file (you could put the PDF on your smart phone and take it with you to shows)

Just like they do for coins, CDN Publishing has a currency CPG (Collector Price Guide, i.e., retail) price guide for free. CDN also publishes the Green Sheet (wholesale bid/ask) for a fee. Typically, you'll find dealers referring to the Green Sheet for prices.

The publication Bank Note Reporter (BNR) includes a price list if you want to subscribe to it.

If you have a Heritage Auctions account (and if you don't then I'd recommend that you get one, it's free), then you can get the Green Sheet and BNR prices on a particular note for free by looking up the last sale of the note you're interested in. You'll not only get the last auction price of the note, but in the write-up on the note Heritage will also indicate the CDN Green Sheet and the BNR prices.

Also, you could (probably should) get one of the various currency books. They'll have pricing information in them that is typically out of date, but is still useful in terms of relative pricing, as well as general currency information.

Personally, to determine what I think is fair price for a note, I'll look at recent ebay and Heritage Auction prices, along with the CDN and BNR prices available from Heritage.

Definitely look at auctions for a good estimate....but if they are truly expensive bills keep the buyer's fee inclusive in your mind when determining price.
