2013 Twenty Dollar Bill W Dog In Window?

Nobody has figured it out yet. Keep trying, will reveal answer tomorrow morning if no one hits on it.

Boy, this thread has really gone wacko. I'll have to make stuff up more often!

Wait a minute....... How much stuff have you made up that we DON'T know about?

Ok, here goes...You can't add to an engraving, it's already flat in that spot. You could only remove an existing dog in the window.

Here's the answer:

The OP's modern $20 note (with the alleged dog) depicts the north elevation of the White House. This design was only adopted in the 1990s. Older $20 notes, such as those used during FDR's time, depict the south elevation of the White House.

In other words, even a hypothetical alteration made in 1945 would not appear on today's version of the $20.

And, of course, no such alteration was ever made.

A swiiiiiiing and a miss! Mighty Kenkat has struck out!

That's why I chose this topic for a teaser - I think many collectors don't realize the White House elevation on the $20s was flipped in the 1990s.
