What are Epicure 3.0 Pyramid speakers worth?

I have a pair of Epicure 3.0 Series II Pyramid speakers that I am considering selling but I need to know how much to ask for them. I re-foamed the woofers and midranges about 15 years ago and had great results except for a rattle in one of the midrange drivers. I replaced both midrange drivers with some unknown name drivers I found at the local electronics store. They (the mids) have a power rating of 200 watts and sound good but are more efficient than the originals so I added l-pads to attenuate them. They now sound as good as the originals minus the rattle. I will include the original midrange drivers for the perfectionist to have rebuilt. The foam tweeter covers are in great shape. The front foam covers have long since disintegrated so I replaced them with round auto stereo speaker grilles. Not original but a good look anyway. I understand these speakers sold for $1000.00+ back in the 70's. Anybody out there have any input?
