I am not sure what it is worth but I received one as a gift from my girlfriend. Tonight, I'm going to shoot with it for the first time. I am going to load it with a 4x5 negative sheet of film.(posted 8266 days ago)You might want to try and sell it to KEH. I think they are based in Georgia and they specialize in buying and selling used camera equipment.
If you didn't expose the roll of film when you opened the back, you might want to get it developed by a pro lab. You never know what might be on that film if it hasn't been completely destroyed by time, heat, humidity, etc.
