A neighbor of mine, Dan Clow, is looking to sell his collection of Danbury Mint lighthouse replicas. He has 27 in all -- lighthouses in the U.S. and elsewhere. They're in perfect condition, all with the original certificates.
Dan will sell the whole collection for $500 (a fraction of what it's worth), or will sell the pieces individually. You can call him with questions: (603) 433-7122 or (603) 759-8123. He's in Portsmouth, NH, so this would be best for someone within driving distance, but I believe he's willing to ship them.
