Here's a scan of the dovetail $1 from The Mint in Las Vegas. Listed in TCR as E1541. The colors on this chip are purple and lavender, not brown and lavender as listed.

By the way, there were at least two of these dovetails at the show, one of each color combination, and I know that one sold for $600, high book in The Chip Rack. Maybe the asterisk can now be removed from the "W" Value Code?
