I was looking through a book published 50 years ago -- "Nevada: Official Bicentennial Book" in which Nevada salutes the 200th USA anniversary. Included are various articles about Nevada history, some fun (dated) ads for casinos, etc. and more.

Included is a half-page article about chip collecting written by Phil Jensen. Here's a pic of the article - taken with my phone, but seems readable.

Phil : You da man! Writing about chipping for 50+years!
