Josh K.I paid just under $400 for a psa 4. So I would guess somewhere around 150 with a common back. Just a guess though.
I should also add, that if you are planning to bid on the psa 2 young that is currently listed on ebay, I would personnaly bid conservatively - it does not look like a particularly nice "2" to me and I think you could probably find better examples.
