Story time! My uncle had some contact in fruit shipping, and noticed that this guy got pallets of mangoes (i think it was) with bottom plate boards that were 3/4th inch mahogany plywood. They'd been burning them as scrap.
He salvaged enough to roof his houses in barns near the Florida coast and never worried about hurricanes. I have a couple chunks of it that have outlived the steel frame of the flatbed cargo trailer they're floor for.
Ah good save, I did see a rough cut 2x4 of tiger maple once, plus a couple sheets of appearance-grade 4x8 red oak... and thankfully I was smart enough to grab those.
Personally I'd use the mahogany ply for something furniture-related if it didn't have ugly knots or cracks in it. It was a rather nice looking wood the few times I've seen it, so it seems a shame to use it for something purely structural.
