can anyone tell me what this is/how rare/how much to sell it for?

if anyone wants it,give me a hollar

Basic Famiclone.  The system is worth around $20 or so, probably around $10-20 for the cart.  Nothing rare, and nothing with any sort of demand.

I just love those multi carts. Just one quicky after another, it is
like being in the land of milk and honey, and I am the last drinker.
