Accurate supply numbers are more meaningful to me. I can determine my own demand. That's the reason I would like yearly guide updates. Being a newbie I receive advice that, "I should research the chip before buying it." A recent dicussion regarding the selling of La Rue chips for $49.99 when they are in the Chip Rack for $600 appeared to center on the fact a "find was made and discussed two years ago at the convention". Well, how do you do determine supply? The authors of the two publications have far more expertise than I will ever have. Yet, they are unable project chip finds that will be made in the future.
