HW: Sonic Attack again (no, not THAT one)!

[Mark Edmonds]

I was wondering if anyone else has come across this pressing oddity.
Years back when I bought my Sonic Attack LP I found that I bought a
pressing which had side A on both sides. I kept hold of it for a while
thinking it might be valuable but eventually sold it off and bought a
correct pressing.

Does anyone know how many were pressed like this and if it has any
collector's value?
