The HCE records and the HCE dies were from different eras.

Mark might add something here, but I never noticed any information on the die tags.
I have had HH ID hubs from the die tags when no card existed. Not much information on the Mason tags either.

I also have had BJ dies searched when no card available. Same as Mason, not much help.

Its funny that companies will pitch old records yet keep the dies.

I think Blanchard told me dies in the era of the one you bought cost $250 or so to make.
A BJ die today costs the customer $135.
