This is the first pine cone found since John Benedict's discovery of some 56 pieces (10 to 11 years ago?). I only found this one chip. Unfortunately it is drilled. Fortunately it is the only brown with black ring known, making it the rarest of the pine cones.

Here is John's discussion of the Cal-Neva rouletts back in 1998:

Damn, USPC made wonderful chips back in 1937.
