It's clear that Pioneer Reference Disc (2001) [GGV1069] is the same as Pioneer Reference Disc [GGV1015], based on the mint markings. I have a Pioneer Reference Disc [GGV1012] which appears to be exactly the same as well. Based on the descriptions, Pioneer Reference Disc CLD-3070 [GGV1002] is the same.

Are all the GGV 8" discs the same? I know there are 2 PAL versions, but they sound the same to me by their descriptions.

I've had this same question. Every service manual I've personally seen so far references the same frame numbers at least. I haven't looked too hard though and could be wrong.

My guess is that the master is different for each part number and even though they are the same content each master can have minor differences. I have the 12” test disc and it came with a note to not use a section of frames for adjustments. Each master could have slight variations that could effect adjustments but I never seen anything from Pioneer stating they are different.
