How rare is the SNES Sonic 4 Pirate Cart:




and how about this 5-in-1 pirate that apparently has Sonic and Knuckles on it? is this true, is it a terrible port or what?



Images borrowed from snes central!!!

I would like to obtain these, as long as they are not in the hundreds of dollars range...in that case maybe a repro would be more reasonable (if possible)
