I've written about this on the boards in the past, but it might not be easily found using the search function on the boards. The model is described in the July, 1988 issue of the Greysheet and as far as I know has not been updated in the 21-years since its inception. I have this issue somewhere, but can tell you from memory that the market indicator is a basket of coins in different grades. I think there are twenty data points used in this market basket from something like a dozen coins. These coins are not entirely representative of the market and include issues like the 1938-D Buffalo nickel in MS63 and MS65 or the 1921 Morgan dollar in MS65. A weighted average is taken of these twenty data points to obtain the numbers that are published.

The greysheet sites says the same as what Tom said. At the link there is also an offer to buy a copy of the full article with a full explanation for $2.50.

In any case, the percentages are not useful, because they are only an indication. Neither the greysheet or the bluesheet actually buys or sells coins. CCE the electronic trading network quotes are closer to reality because people buy actual coins and pay actual money. A person could say that the greysheet indicator is for theoretical coins, and for collectors that are interested in theoretical coins. That may sound silly, but for a lot of forum polls, theoretical coins are often involved, instead of actual examples.
