Ed, there are three in David Niver's Colorado guide that have a book value of $300 to $400. They are:

Fully reeded, gold eagle, silver rim, silver feet, silver branch / silver reverse, brim hat, neck halter and no ripples

Partly reeded, gold eagle, gold rim, silver feet, silver branch / gold center, brim hat, nose halter and no ripples

Partly reeded, gold eagle, gold rim, gold feet, gold branch / gold center, brim hat, neck halter and no ripples

You could also be thinking about the Colorado Gold Rush eagle on the Saloon #10 $28 from Deadwood. It's a Deadwood error with a muled die, that one still has a good value.

Dave.
