This post and the replies are a great example of why I love this hobby (and the chipboard) so much!
What a wealth of information that is being shared in the course of a handful of very very interesting posts.
Starting out with a question that I am sure many of us have, then getting expert insight into the answers, plus a bunch of jeton-related great human interest stories. (including Scott's picture of the jetons he won in the club auction last year - a lot that I bid, on but clearly not enough.
Thanks to everyone for sharing the great info!
