Lurker is a strange description for yourself, must be a previous conviction. I happen to think James' book on a whole when comparing 20,000 chip values is more accurate than TCR and you will find half the hobby saying the same thing. The other half like the TCR. My experience is that if you can buy chips are TCR prices, buy all you can. You wouldn't know that though, being a lurker and all. If you even knew who James Campiglia is, you would know that he is probably the most knowledgable person today on chip rarities. Compare 500 chips from the TCR to James' book and you will get 250 that don't match up. But you wouldn't know that either, being a closet collector and lurker.
