What can market do with prices of stamps is really crazy


I start collecting first issue stamps, and compare prices for them...
First issue of USA: issued:
3,717,500 copies, price for good example:
250 - 400USD7th issue of Solomon Islands: issued:
only 7,281 copies!, price for good example: 70USD, price for first issue (
45,364 copies) is 8USD?
