Note: Info is correct as far as it goes, but, unlike
with other serial numbers you've done, YOU DID NOT
INCLUDE THE RUN TOTAL which is important in
determining rarity.

Curator Response: Run total is not included because these runs are fairly mixed, and run totals and estimated production would be wildly incorrect. Hopefully, more research can be compelted in the near future to provide better insight into how these runs may be split.
