I had one with no barcode actually I got in a CD lot that had super rare bay shit back in 05 or 06.
I sold it on here actually, I forgot who I sold it to though because it was back in like 06, I got like 150 for it but I'm sure its worth more now.
It had a barcode but it was blacked out in orange, I had a Settirppn cd that was like that too.
Both had no ring codes, I think they were both pomos? IDK.
