Player Focus: Andrew Bynum Auto Variations

As all of you have noticed, the way that some players sign their names vary, depending on the year it was signed, or in some cases the product that was signed. Kobe Bryant's autograph evolved from Kobe Bryant, to Kobe 8, to just Kobe. Andrew Bynum, just within his RC year has three different auto variations: AB #17, A Bynum and A Bynum #17. In the case of Kobe, there's a premium for his full name signature, because he only signed it that way for a short time during his 1st year. Of the Bynum autos, the products that have each variation are: "AB #17" - all Topps products, Reflections, SP Game Used, SPx, UD Hardcourt, UD Rookie Debut & UD Portraits. For "A Bynum" - Exquisite Collection, SP Authentic, Ultimate Collection & UD Trilogy. For "A Bynum #17" - SP Signature, UD Portraits & UD Sweet Shot. Based on this rough info, I would say that the AB #17 would probably be the most abundant (and possibly the lowest long term value), while the other two would have the most potential value, due to 1) the high end products that have the A Bynum version, and 2) only two products having the A Bynum #17 version. Also, players' sigs don't usually get longer, they tend to get shorter, or more abbreviated over the years, so I would guess that the AB #17 might be the one to persist in future year products, making the other two variations more scarce and command more of a premium as time goes on. The other x factor is that we don't know the population for the autos that aren't serial #'d, so it's very hard to get an accurate count of how many of each really exist.

If you anyone out there knows which variation is usedUD Rookie Debut, please let me know! Thanks.
