A little Help with Rawlings Codes,

I'm confused by it all.
I have two Heart of the Hides, one a Pro-1000BC marked BBB01, the other a Pro-1000H marked CEC14, any help would be appreciated.
Both are marked Made in the USA, but I notice the leather on the Pro-1000H seems heavier than the 1000BC
Thank you.
