Bob, thanks for your great information.

Can you clarify something for me? In your post you said "(Note: they never made a $50 in the dragon mold)." Is what you meant to say is that "they never made a $50 in the DIAMOND mold"?

I ask because when I look at the TCR 20 they show $50 in a dragon mold (which I have) and a $50 in a Mermaid Mold (which you show show with your diamond mold chips).

That is also consistent with the Chip Guide which shows a $50 in Dragon mold (and they have a picture). They list a $50 in a diamond mold, but don't have a picture (which leads me to believe it doesn't exist and it's listing is in error). They also don't list/show the $50 in the mermaid mold that you have. If you are saying it was the chip issued with the other denominations in diamond mold, you may consider submitting it as a correction to the Chip Guide.

Thanks,
- Bob M
