Cool token. Seems like I remember Namco being a manufacturer of some of the old Atari games back when I had my Atari 2600. The good old days.
I like old tokens too. Ive been finding the hell out of tax tokens lately. I think I have found 3 in the past week or so. All MS, AL, LA., but I prefer the older trade tokens which are a little more rare.
That book "Brozenes and Doodlum", is a pretty good book. I have seen some on the site Andy posted that weren't in the book, but between that book and the site Andy posted on his token thread, you cant go wrong.
I bought mine on ebay for $37 after shipping a few months ago. So $40 seems like the going rate.
A couple more good books if you like old Military Buttons.
"Uniform Buttons of the United States, 1776-1865 by Warren Tice"
"Record of American Uniform and Historical Buttons HC Book Alphaeus Albert 1976"
They could be in your library too.
