Thanks guys. It is a starter mesh plate. I scored a pretty trashed jersey a while back for like $40 & using it for plates.
Here's what I know of the Avs jersey history & construction - mostly from http://www.eddiesjerseyroom.com/ and personal conversations with folks at Denver Athletic and the Avs trainer (who was at DA one day when I was there picking up a jersey)
* '95/96 First generation number font, some asymmetrical letters- 3 layer stacked - probably lettered by Starter (This is just my personal assumption. Anyone with info to the contrary - I'd love to hear what you know)
* '96/97 First generation font, no more asymmetrical letters, slight changes to other letters as well - Some form of kiss cut number construction, no longer 3 layer stack - Still probably lettered by Starter......Until around the playoffs, when gamers appear with one number 1st gen. font and the other 2nd gen. font (mostly #1s in 2nd gen) on the same jersey. Then for the playoff jersey set the numbers all changed to 2nd gen. font- presumably still kiss cut - and possibly due to lettering contract being taken over by someone else (again, anyone with more info, please......)
* '97/98 Full 2nd generation number font - still kiss cut - not sure who lettered the jerseys. From a conversation I had with Nate at Denver Athletic they never kiss cut until the Edge jerseys and he couldn't remember when they took over the contract for the Avs, so if '97/98 gamers are kiss cut it makes sense to assume that DA didn't do these jerseys
* '98/99 2nd gen font - All 3 layer stack and presumably due to the change in construction this must have been when DA took over.
* '99/00 ProPlayer jerseys, same construction as previous year
* '00/01 CCM/Koho jerseys, same construction
* Nate at DA says they didn't start kiss cutting numbers until Edge jerseys started, but I've heard elsewhere that they started doing it when Reebok took over.
So, there you go. That's what I know (or think I know).
