3 (possibly) dead NES carts for trade

[MegaManFan]

I have a Big Nose with the switch in the back that I've never been able to make work on my top-loader. One way it blue screens, the other way it rolls. I spent $5 on it though, so I'd like to get something decent for it if anyone's interested. I'll throw in copies of Athena and SMB/DH for free that I can't get to work even though I've cleaned them repeatedly. I'd take a couple good 2600 or 5200 games I don't have in trade if anybody's interested. No takers I'll probably list them on eBay after the 1st of the year as "3 non-working NES" with a $5 BIN.
