Pete... that's exactly what it means. Negative numbers indicate how many have been destroyed.

Thanks, I never noticed that before and it adds to the useful information.

I also liked the part about consolidation of the LCV and SCV (which are AKA raised cane and lower cane varieties) because some of those chips, were ordered and made at the same time with the different molds.

Not Las Vegas, but someone had to point out to me the Wisconsin chip that was issued with LCV on one side and traditional H&C on the other. That's a treat!
