the 5-5000 were paulsons and the the 10,000's and up were budjones metal inlay chips. they used these chips from early 90's to 2003, this is the chip.
they just mixed the chip makes, they made the 5000 chip budjones a lil after so if you have a paulson 5000, most likely from early 90's.

they changed it around 99-00 im sure. the 5's were used as antes then they took them out, and just had the 25's and up, the ($5)25's -5000 were paulsons and 10,000 and up were bud jones pre 99 and the 25-1000's were paulsons still but the 5000 and up were bud jones post 99-00.
if you need fact, just watch the 2003 wsop. and watch previous wsop final tables in the 90's
but those chips above, 95-1999(the 5000 changed)-2003.
then the chips became all bud jones, then all paulson year 07.
