I noticed some JC hourglass mold chips in the Chip Guide as being from the Jockey Club in Newport, Ky. I notice one has a ring around the JC and one does not. Is that of any importance? Where did these ID's come from. I have a yellow JC $1 chip with the same hourglass mold.. I have all three chips and I did get them all in the Northern Ky area...........
