A few years ago I came across a Rally IV console at a thrift store. I'm moving to another state and I'm looking to slim down my gaming collection. The problem is I have no idea how much I can sell this thing for. It's in great condition and the original box is in decent shape. Sadly, I don't know what became of the instruction booklet. It was made in 1977 and plays squash, tennis, hockey, and has a practice game. The game variants are selected by turning a dial. Does anyone know how much I can get for this thing? I've included a picture below. Although it isn't my particular console and box, mine looks exactly the same.

Rally consoles are VERY hit or miss. But I heard from a friend, he passed four years ago, that he sold his for about $160.00 US. Not as much I thought it would go for, but apparently that was a solid price. "
