Gibson ES-335 1963 50th Anni serial numbers help

[joedonner2001]

I've been looking at some demo videos of this model, which I believe came out in 2013 (funnily enough ), but the serial numbers seem somewhat strange to me.

E.g. from various Wildwood videos:

08533
37133
28342
15914
02056
08561

What's the trick to understanding them? I don't recognise any convention there.

THey are based upon the way the serials were in 63. No rhyme or reason.

Historically accurate confusion. I like that.
