It would almost have to be a type of Chinese or Chinese hybrid if it is very old at all. There are a few american chestnuts left out there but they are very few and far between. Michigan has a decent stand, I believe.

We have a large Chinese at my great grandma's old house that came from Auburn. If there is only one tree there though, the nuts most likely won't be viable. The ones from that tree aren't. I'm planting a Dunstan nearby and will create a new hybrid in a few years from the two.
