The 2005 reunion are the rarest of thumbnails made with only 450 made of each. Collectors are starting to realize that these thumbnails are harder to find than the older ones that had a production of 850 to 2000, which usually goes for around $32.
The one that goes for $15 is the Hereford and at this time it is cheapest because most collectors got one with their Collectors Hooper Strait.

Any Harbour Light with a production of 500 of less will demand a good secondary market.
