Tokens, unlike coins, have no established market value. If you buy a copy of the coin "Redbook", A Guidebook to US Coins, you can come pretty close to establishing a coin's value from it. Tokens, on the other hand, don't have as large a base - fewer collectors, and fewer tokens have been found. Plus the way tokens are collected is different: most collectors only want one of the state, town, merchant, or variety whereas there are collectors who collect rolls of certain coins.
When it comes to values, a printed state token catalog is really only good for knowing whether the token was known to the cataloguer at the time of publication. Few cataloguers have access to all of the major collections in his area, let alone the finds of metal detectorists and others who may have tokens. So, the population shown in a catalog is at best a guess, and valuations shown are really a guess.
The only way to evaluate a token is to let the market decide - a willing buyer and a willing seller. But keep in mind that if a certain token sells for $x, a subsequent sale value will probably be different because the transaction will be between a different set of buyers and sellers.
Online auctions are a pretty good gauge of value, but you may go decades without seeing a certain token come up for auction, so you must be willing to put yours up for sale. Or, you could consider joining one of the national or regional token collecting groups - there you could show your token to others and get offers.
