Not at all.
I have always said that Harbour Lights is a company that is in business to make a profit.
I am in the business of collecting lighthouses because I like them and the history that is associated with the Lighthouse Service.
I buy the pieces I like and don't buy the ones that I don't like. It is that simple. Every piece that they produce that I like, adds to my collection which is displayed in my home for my enjoyment.

So enjoy your collection and don't worry about the secondary market or the resale value down the road.

Life is too short.
