Sony PSP Proto/Preview Copies

I have these two PSP prototype/preview UMDs for Ratchet & Clank and Gurumin. Any idea how much these are worth?

I had Test Sample PSP versions of Killzone and some soccer game. I sold them on ebay a few years ago for about $30 each.

Ah, that's about the vicinity I figured. Thanks!
