Nice going Prismatic. Is there logic or math behind this solution or trial and error?

I thought about it for a while, but I couldn't see an analytic solution to the problem.Nice going Prismatic. Is there logic or math behind this solution or trial and error?
So I just wrote a little program to solve it. By the way, there are no other solutions.

yes indeed, superprismatic. when i first composed this puzzle, did not know that it had been thoroughly investigated. and often with the same postage stamp theme. from what i can tell, a universal solution yet evades number theorists. dont have any programming skills to speak of myself so was limited to a spreadsheet. the highest i got was 115.

A possible extension: What is the highest maximum postal price for which this problem has a solution?

According to the premise
between $.01 - $1.26 (inclusive)
it seems to be $1.25
1 + 4 31s.

What I meant was that if you changed $1.26 to something higher, what is the highest value for which there is still a solution with 5 stamps?
