Overhauled, 108" (-12's), A grade (so the absolute top dollar) seems to be in the high teen's right now. I've seen them advertised recently for $18k-$20k.
We recently (a little under two years ago) bought a prop quite similar to your description (-18, A grade blades, packaged and likely NOS) for I think $6500 or $7500, then it took us $4k to get it overhauled.
I'd say going rate for those props overhaul'd would be in $11k->$14k, depending on where you advertise them and how quickly you want to sell.

Any Goose owners need a set of props ?
We'd like a spare set of props for ours - but there aren't any Gooses left in the world running 2D30's. 2D30's were original equipment, but everyone is running 3 bladed Hartzells except us and we are running 22D30's. Running a Goose with non-feathering props is a bit of a gamble in my opinion.
