In regards to Darren Becker's Puck Guide which is out of print and out of date, most info is now on his puck site, www.officialgamepuck.com. There is no price guide, just images of each puck and sometimes dates or history. A great site.
What are you looking for? I have tons (1000 or more) of old pucks from 50's/60's through 1980's minor pro, amateurs, olympics, orig 6 NHL game pucks, WHA, European (70's era), Canadian & US Senior leagues, Women's pro teams of recent years and have a full official game puck collection from ECHL (maybe late 90's/early 2000's), some college pucks from 1970's.
Most of my collection is from 50's to 70's. some very rare pucks. Most acquired from teams directly.
I also have sporting good manufacturer pucks from Draper Maynard, Art Ross, Spalding and others.
I have an ultra rare Draper Maynard hockey stick from 1920's, maybe 1930's. Extremely difficult to find anywhere as produced in limited run.
