Legitimate Charity

I’m thinking of giving some peer coin to a good cause. Does anyone know of a legitimate (registered as a non-profit) charity I could contribute to? I’m thinking of giving 10 percent of my sales to a charity but can’t pick one. Does anyone have any suggestions? It doesn’t have to accept crypto coins necessarily, just paypal or something local (live in TN, USA)

I think I’l spread it around. Hopefully this would be around 10 ppc apiece, for a goal of 100. Not much to some but could mean something to someone.
