I have a set of suntour radius cranks and they have a stamp. its not the traditional njs stamps i see. can someone please identify? this isn't the actual part but its the identical stamping

It's just a JIS stamp; it basically means the part is manufactured to Japanese manufacturing standards. Think ISO standards and the like.

Unfortunately for you this stamp doesn't make it worth more. Sorry about that. =/

alrighty thanks, wasn't really hoping for more value in my parts just wondering because i have never seen it before.

No problem
