Hotwheels for sale

My grandmother is passing away soon and we are going to have to sell the house once she does. I was wondering if there was anywhere that I could sell about 200-300 hotwheels? They’re all in great shape, about 70 of them are Premium/Real Riders. I’m not looking to make a fortune , but I’m also not trying to get completely screwed. All the offers I’ve gotten on 5mile and offer up are just complete lowball offers. Any help is appreciated than you! (Also I live in humble so somewhere around here would be nice)
