Krusty--Crawford & Farber's Louisiana Trade Tokens book (available at
TAMS Home) pretty much copies what Trantow's Lumber Tokens book says. They do add a "desirability" rating of C on a scale from A to G with A being highest.
There is no standard for token rarity. That is because the hobby and resulting marketplace has not matured like that for coins. It is relatively easy to find the buy and sell prices for a given United States coin. There are books, online lists, dealers in most larger towns, etc. etc. Trade tokens, on the other hand, have only been seriously collected for 50 or so years and new discoveries are popping up daily - thanks in a large part to metal detectorists. There are so many different tokens out there that a collector almost has to specialize (or have deep pockets). Most specialize by state - the first state catalogs were put out in the 1960s and some states have yet to have a catalog written. One of the early catalogs had a 1-7 rarity scale. I've seen several other scales, including the 1-10 scale. But keep in mind that rarity does not equate to value. Supply, desirability and demand are the main factors in determining token values. Some states and types of tokens are way more popular than others.
When someone takes on the task of writing a state token catalog, that person only knows what others are willing to tell him when it comes to rarity. Many people might tell the cataloger that they have a certain token, but might not want it known that they have a dozen others just like it. Letting that info out would kill the value of what they have. Human nature...
If you are interested in collecting trade tokens as a hobby, it would pay to get a copy of the books for the areas of your interest. And then join one of the token groups so you can meet others with similar interests. Tokens are fascinating bits of history and can be studied as deeply as you want.
