Dave--and in answer to the other part of your question - what it books for - the NE book gives neither rarity or prices. The hobby of token collecting is not as well-developed as that of collecting US coins and there are way fewer collectors. So the prices one can expect to get for a token often depends on whether a piece is offered to the right collectors at the right time. It really takes at least two competing collectors who want the piece to drive the price up. To find those collectors, you have to find the venue where they are both looking at the same time. This can be a major token show - the NTCA one is coming up over Labor Day weekend at Fargo, ND, for instance - or you can use eBay for probably even wider exposure. Another factor is the popularity of the state. An "unlisted" merchant from Utah will bring more than an equivalent piece from Nebraska now. This popularity changes over time, but in general, tokens from west of the Rockies command higher prices than those from east of the Rockies.
