Hello:

The MINT chip (from what I can see in your scan) is #N6731 in the 6th edition, dated June 14, 1999 Chip Rack and was used in the 1960s..............Value is $75-$99 according to the book.

The FLAMINGO is #N1610 and was used in 1967, value is $75-$99.

Remember a chip is worth what a buyer will pay. The Chip Rack is only a guide.

Good luck and you got two very nice chips.................Jim
