hi...
i remember is being about 14" high. i saw it at the christie's auction and in the christie's auction book, the actual height is not listed. however, the listing is as follows:
Auction # 691 (found on p.95)
Enterprise-D core section modela visual effects model made from styrene plastic and other mateials, representing a piece of the Enterprise-D saucer section, revealing detail on several interior decks, the "core section" was taken from the ship in a Borg attack, in two sections, each - 16Ωin. wide - featured in "Q, Who?" in star trek: the next generation
$1,000-1,500
i'm not sure what the winning bid was as i wasn't interested in following this piece. if it followed the trend of other pieces, it probably went for 3x that.
hope that was helpful.
