This week, while visiting family up north, I was able to root through my grandfather's shop. He passed about seven years ago. I loaded the new truck to the top with various woods left behind. Most notably, 10 boards 14-18'' wide 4/4 14 ft long rough mahogany. My father puts this lumber at 35+ years old. My question is how do you tell if this is the "real deal" maho, which is very valuable vs. phillipene maho. If I have the real thing then I would greatly consider selling this material in order to stock up on lumber I like more (not the biggest mahogany fan). Any tips for ID would be appreciated.
