Atlas Mason Jar

what do the numbers on the bottom of blue ball mason jars mean?

I see on Ebay someone said #13 was rare. Then others have numbers 1, 2, 7, 2 F, etc.
what do these numbers on the bottom of these blue and clear Atlas and Ball jars mean?
well a 13 is selling for $20 and a 2 is selling for $5 so there must be some difference.

its the mold number the jar was cast from
