What's the difference in 5screw cib zelda guts and box verse the 3 screw version? Looks like same map and instruction yet value is 100$ more gvn shows 72$ 3screw cib and 170$ 5 screw

From my limited knowledge, I think the main difference is the 5 screw version doesn't have Rev-a stamped on the box and manual.

First 2 print runs were 5 screw, and only available for the latter half of 1987. Finding one in nicer shape is tough just like any 85-87 releases, so people are willing to pay a premium for early prints in above average condition, especially for one of the most beloved games of all time.
