Are CGC "old" labels worth less than new ones?

Recently, some of the books I've accumulated have been great deals, and I noticed that some of these are the "old" style CGC Universal grades. Comparing to other books on auction sites (ebay cough cough) and some cons, are the older CGC labels considered less valuable or am I making something out of nothing? Any thoughts from others? Is this a recent trend?

I'd rather have all "matching" labels, but in the end I don't care, I just want to know that my 9.8 is a 9.8 is a 9.8.

Or in some cases, my 3.0 is a 3.0 is a 3.0 haha.
