Question about KC Pro ROC's.

I've had this disc for a long time, but now I'm a little more curious about it. It's a KC Pro with no #x on it. It's very powdery(sp?) and has a very noticable dimple in it's center on top. Does anyone have a clue as to how old or what series run this was?
Thanks for the help!

It's newer than a 9X.
Because the stamp (what's left of it) gives that away.

I've asked this question before and I was told they were run between the 11 and 12 time rocs. Why they didn't put a "time" on them is beyond me. These are my preferred kc rocs though.

Mine also! If I need it absolutely straight at any speed, I grab This disc! It has two of my three ace's on it!

These are 11x KC Pro Rocs that were not stamped with the 11x Ken Climo Hotstamp.
I only see a handful floating around. We keep them in our Collector section under Roc.
The 11x KC Pro Rocs are sought after because this was a great run of stiff plastic with consistency.

That is identical to mine, except for one thing. Where yours says 'Mid-Range', mine has 'Multi-Purpose' in it's place. Maybe that'll help as a clue also?

It is just a hotstamp and doesn't have much to do with the disc plastic or mold.
If you look in the Roc section of the Collectors, There are both stamps on the Blank Rocs.
It is the same disc (plastic and mold) as the ones stamped with the 11x Ken Climo Hotstamp.
I do not do the marketing for these companies, I just roll with it!
