What does Uhqr mean concerning records?

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.
