What does Uhqr mean concerning records?


My turntable is in the garage and I'm contemplating bringing it back out, but I have no idea what the above letters mean. Anyone help?

Thanks,

At the outrageous price sellers ask for one, you'd get much better sound from Better Record's white hot stampers with an equally lighter wallet.
Can anyone give a realistic price range for these UHQR's from decent shape and used to unopened, still sealed and new in box?

And by that, I dont mean buy it now for $1 MM, but prices where they would actually trade.

I am from the school of thought that generally speaking, audio has gotten steadily worse since about 1989, and can also recommend them.

For only a few $1800 sales, I bet I could buy my own sealing machine.

So I have always wondered how do you know if its really new and/or how many times a used or even empty UHQRs passed through several hands as "new"?

Not to make anyone paranoid - they are otherwise good recordings.
