Oldest thing you have came across.

The oldest was also perhaps the hardest thing I ever scrapped. A 100+ old piano. I first had a piano person look at it, she told me a lot about it, most important information, was in her opinion, the old upright piano could not be restored. I did the piano demo, surgically because I wanted to save as much wood as I could. The wood was old-wood, tight grains that is hard to find these days. There was only three original "Ivory" keys, the rest had been replaced with plastic keys. I was surprised and as a coin collector, very happy about the amount of old US coins that were inside this old piano. This piano breakdown was not easy, the metals counting the coins: Silver, Copper, Brass, Steel, Cast Iron, with some nice old wood and a little Ivory too!
