Hi Greg!

I just did some more research.

There are 2 different $5000 chips

If its Beige with house mold and 4 blue and 4 pink splits its extremly rare and probably worth around $1500

If its Maroon House Mold with 6 white and 2 Yellow Splits
Its very very common and worth about $70

The $25,000
should be Orange and House mold with 3 purple 3 brown its also very common should sell for around $100

Hope that helps you and welcome to the hobby.

Rene
