Here's an interesting oversize large value chip. I don't know what it was used for but would guess Oriental Pearl is an offshore ship in the far east somewhere. This Paul-son chip is 50 mm in diameter and has a hologram of the hat-and-cane in the center behind the denomination. There are no molded devices on the rim. Notice it is also appears to be serialized but the number is not hotstamped; it's printed on the inlay. Maybe that's a date in 1974?? Anyone have any info on this?
