Hi to all.

I have a Jimmy Page and Robert Plant signed Led Zeppelin Whole Lotta Love / Immigrant Song 7" record sleeve which I am considering putting up for sale.  My problem is I do not know what a reasonable price is for such a piece, as when I've looked prices seem to vary wildly.

The story I have is that it was signed after their press conference in Istanbul in 1998.  Both Roger Epperson and PSA/DNA have given it the thumbs up (quick opinion on both).  So can anyone tell me what would be a good price (or price bracket) to put this up for?

Here is a pic of the item:
