Well nobody really "asked", but here's an at-random sampling of a few of the lights and their published worth from the CIB' Collectible's Market Guide & Price Index (19th ed.):
#236 Old Mission Point $70
#153 Round Island $105 - $221
#148 New Canal $90 - $105
#172 Chatham $100 - $171
#214 Bass Harbor $75 - $130
@219 Gay Head $75 - $219
The one that I inquired about would be just on Harbour Lights and not all these other companies and their products, plus may be a little bit more adjusted (up or down) perhaps!?!
