Do you happen to own an oak forest? Then you might be rich. A cooper in Bordeaux just paid 37,790 euro for a single oak. But it was not just any oak: it was 340 years old, so planted around 1660, 39 m high, a diameter of 1.3 m (not much compared to the Swedish Rumskulla oak (pictures here) oak that is 4 m in diameter), and a volume of 19 cubic meters.
