I collect antiques and other odds and ends...
Furniture: antique table (1), antique dressers (2), antique clocks (2) - one is a mantle clock that chimes every 15 minutes with the Westminster Chime (Gustav Becker movement).
American Pocket Watches (7): Oldest one is from 1890, one is my great grandfather's that he received as a high school graduation gift, another is a Waltham Appleton Tracy model Rail Road Watch with 17 jewels with beautiful damaskeening.
Several wrist watches: Swiss and Japanese.
Old photographs of my family from about 100 years ago.
Mark Twain books and essays.
A few old coins: one of which is a 1940's stainless steel penny. These were made during WWII since copper was used for the war effort.
