Did any of you catch Antiques Roadshow on educational TV last night? I only caught the last half or so of the segment so my facts may not all be exact.
This fella (I believe he was from California) was digging in his back yard and found a big cylindrical object. As he was cleaning it up he was washing out the opening with a hose when water started coming out a little hole at the opposite end--he said that was when he realized it was a cannon.
The appraiser found lots of markings on it (it was a mountain howitzer) such as the date (1853- I believe he said), the weight, who made it, the initials of who tested it and the US stamp of acceptance.
Its' green patena was almost unbelievable. The owner said he, at one time, thought of selling it for scrap brass, to which the appraiser informed him that it was bronze. When asked the canned question about value, he said he had seen a reproduction once, priced at $10K (which more than likely was the whole setup--carriage and all). Anyway, the appraiser gave him a range of (if I remember correctly) $30 to 40K.
I felt like grabbing a shovel and heading for my back yard!
