A new book profiles amateur inventors from around the country. We'll find out about the people who really are building better mousetraps and all kinds of strange things, like motorized walking tables and shirts made out of computer fans. Shay's guest is Bob Parks, author of Makers: All Kinds of People Making Amazing Things In Their Backyard, Basement or Garage. The book is published by the people at Make Magazine.

We'll also check in with coin expert David Bowers to find out if the state's highway tokens are worth more dead than alive. The state toll collectors will stop accepting the special coins as of January 1st to make way for the new E-Z Pass system. That could make the tokens attractive in the eye of collectors, but maybe not enough to gain much value. David Bowers is numismatic director at American Numismatic Rarities in Wolfeboro.
