Welcome Charlie. You've got "good taste" if you're collecting Harbour Lights and have 150 already!
What part of the
ocean country are you from?
On the 'net, TYPING IN ALL CAPITALS is considered "SHOUTING". Just hit that Caps Lock key above the SHIFT key to get back to lower case!
You asked about disposing of some of your pieces. First thing is to make a list and check each piece. Potential buyers will want to know the condition, whether you have the box and certificate, whether it has been signed (and by who) and the edition (serial) number of the piece. Once you have that, post in the TRADING POST forum starting with a list of a few of the pieces.
Tell us about your collection - how you got started, which regions or types of lights you like to collect, whether your SO thinks it's nice for you to have a hobby or if you are totally WACKO.
