1951 Topps Redbacks - Complete Set of Panels

[mab]

I am trying to determine a fair price. This set is comprised of 52 cards, plus two variations of two of those cards. The cards were issued both individually, as well as in 2-card panels. I collect both the individual cards, as well as the panels, though I only have 5 panels.

I've come across a set of panels being sold for $1,500. 11 of the panels are graded, and range from PSA-4s to PSA-8, with most being 4s or 5s. The other panels are raw and seem to be pretty nice (EX or better), but I am basing that on scans.

Anyone out there have experience with these panels, and any thoughts on the price? I think it's pretty fair, as I've paid $65 on up for the panels I do own. This would be the most I've ever paid for a set of cards, so I'm a bit nervous.

As a side not, I will be attending the National. Is this the type of set I could expect to find there?

Thanks!
