Sell or keep 2600 heavy sixer woodgrain?

So I have a 2600, tons of controllers and games etc. But I hardly ever use it since I have a 7800 that can use the same games and controllers. I feel like id regret selling, but I have so many systems.

Worth holding onto? They dont seem to sell for much. I have the space for it but I also would like to see someone else enjoy it..
