1989 Fleer Codes
 

I know this is probably captured elsewhere, but just quickly - I know how to read the production codes on 1989 Fleer cases to find the early print runs, but do the codes on the wax wrappers mean anything? I have 2 which are 6813-A. Does this provide any sort of hint as to where in the print run the pack came from?

I don't believe so. Maybe the printer used or the sorting location - but I'm not aware of anything specific.

Your best bet is Google and/or contacting a product reseller like BBCE or JustCollect.
