State Quarter experts - what do I do now? (fixed links)

Notice the missing mint mark. I removed this from a US Mint mixed bag (1999-2000).

Lurking with intent to loom
I own a book on coin errors, I will reread the section on grease filled dies. Thanks for the collective wisdom.

Struck thru grease is caused by a glob of grease dropping out of the machinery onto the planchet or die.
Filled die is a build up of crud in the shallow design areas.
