I highly recommend Steve Boyett Insurance at
www.antiqueguninsurance.com. They will insure up to $250,000 without appraisal. You can list items individually with value, or you can do a lump coverage and specify what the maximum value is for any single item or you can do a combination. They carry both collectors and dealers insurance, the prices are very reasonable and given the lack of an appraisal needed if insuring below $250K it is very simple to set up. The first step is to go to the website and complete the introductory form and they will contact you.
