When do we celebrate Lincoln's Doctor's Dog?

Very true. But I think it was Du Bois's widely read article that rekindled the idea in black circles (while the cultural fad in the 1900-1930 period of glamorizing antebellum Southern culture was doing it in white circles) after several decades of black hagiography (see, for example, Booker T. Washington).

The first redesigned penny (the front stays the same) was released today with the other 3 to follow throughout the year.

Cool!

It looks cheap.

It's a penny.

A cool penny.

(I like the last one best, mostly because "one cent" is written straight across rather than curved or off to the side. I can't think of another coin that has it like that-- I find it very aesthetically pleasing.)

A penny that costs 2 cents to produce, no doubt.

And that they'll sell collector mint editions of for 25 cents.

True, but for reasons having nothing to do with the design on it.
