I don't see the MNHOG stamp becoming valuable, for the usual reason: too many zillions were printed.
But I could imagine a minor custom covers market springing-up if/as he goes to trial.
Now's the time to begin buying the *other* stamps that you might need for those covers:
- International Year of the Woman stamps
- Against Violence Against Women stamps
- Strong women who might have complained sooner stamps (Eleanor? Jeanne d'Arc? Janis?)
- Magna Carta (and other trial-by-jury) stamps (for the day jury selection begins and/or is completed) (if)
- Other villainous men stamps (so few to choose from, eh?)
And, you will need to pick the dates on which to use those stamps, eg, day testimony begins, day BC testifies (if), day testimony ends, day judgement entered, day sentence pronounced, etc.
And, the sentence opens-up all sorts of possibilities: adding 10-cent definitives if he gets ten years, etc.
And, don't forget the wolf-in-sheep's clothing stamps ... you can still buy those se tenant sheets of the US Jekyl-Hyde stamps for less than face value.
