There were 7 figures in the series: Aaron, Bernard, Moishe, Emil, Tzippy, Max & Goat Boy (2-figure pack). I would imagine if nearly 400 were sold that day, then there are nearly 400 signed figures out there, as I can't imagine too many folks in that scenario buying a figure and then beating feet without also getting it signed.
Only sale of a signed one I could find was last December for $83 on eBay:
