It doesn't exist.

I have never heard about.
Its 10,20,30,40, over 40 right?
"40" and "Over 40" are the same designation. As I recall, it is listed as "40" in Europe and "Over 40" or "40+" in the US.
Officially, 10, 20, 30, and 40 (or 40+) are the only ages the IVDP allows for Tawnies with an Indication of Age. Though a while back (8-10 years?... it was roughly 2006, I think) Porto Rocha was able to bottle and sell a "Glorious 50th Anniversary" Tawny Port. I believe that it was technically a Tawny Reserve for IVDP purposes, and not a Tawny with an Indication of Age.
But for Garrafeira Particular, or for Vinho Generoso, all bets are off.

They can't be labeled and shipped as Port, but if a winemaker wants to hand you a bottle from his personal stock... let's just say that I've seen all kinds of crazy old Ports from family barrels that aren't official as far as the IVDP is concerned, and I'm sure that Roy and Andy have seen many, many more than I have.
