Not a 1877 cent, but proof that PCGS will go pretty low... http://coins.ha.com/common/photoDisplay.php?id=1143100039 For extra credit -- attribute it!
I'm hardly above bidding on or buying dog coins if I think the coin is cool despite the fleas. However, this one's more of a "Buy the slab, not the coin" piece, whose target audience is someone who absolutely has to have it for their lowball PCGS Registry set. If I want to put together that kind of set, I'll buy the coins raw and send them in myself. This piece will sell, and it will sell for more than I think it's worth.
