Ted - Seeing what they SOLD for on EBay is a place to start but generally speaking the pieces you have listed are only worth 20% to 25% of retail without the boxes and paperwork and in some cases even less. If you need retail prices go to the 4th Down from the top Forum entitled www.harbourlights.com
and click to open this Forum. The top subject in this Forum is one entitled New Page on HarbourLights.com and click to open. Go to the last post and you will see a link to the retail prices. Click to open and than look up each lighthouse by HL number.
I would suggest that you list them in the TRADING POST Forum at 20% of retail and see how you do. You can only post ONCE A MONTH on the Trading Post Forum so do not think you can change prices during this month period.
The list you have above is fine, except add a serial number and price for each piece. NO IMAGES ALLOWED on the Trading Post Forum and signed pieces may add a few dollars value but not usually. The chances of selling them all in a super package is slim to none so you can mention this but I think separately is the way you will sell some.
Make sure you mention individual shipping charges and that you will combine purchases for a shipping discount. Also make sure you give your email address and phone number (Optional). You CANNOT list any other lighthouse except for Harbour Lights so DO NOT list the other brands in your original post.
