When last we left "the Case of the Penny Plunderers", Joe Coyne had pretensions of remaking himself as a "villain" rather than a mere crook by hewing to a lunatic "crime symbol". Using the power of free association that allows them to divine the schemes of the madmen they fight, Batman and Robin have not only figured out, just by reading the paper, that there is a "Penny Plunderer", but they've divined his next target.
The One-Penny Black, by the way, is a real thing. Golden Age writers like Bill Finger used to hang out in illicit trivia dens in Chinatown, lying on divans, soaking in all sorts of bizarre useless data that they might later incorporate into some plot point. You kids, with your internet, you know nothing of sacrifice.
The first appearance of the Giant Penny. And the much less famous Giant Stamp Tongs.
Rather than alert the police (because, you know, where's the fun in that?), they just lurk around in the shadows, until Coyne and his gang show up, whereupon there's lot of Patented Punning & Punching. And Batman showboating by means of functional giant props.
Just once I'd like to see one of those props turn out to be paper mache, so I could see Batman go crashing through it to a faceplant on the hard, cold floor, while the photographers from Picture News go to town. But I'm sure that's against the Gotham City Civil Code on Giant Props.
But sometimes the gods punish hubris immediately and Batman pays for his showboating with...
a roll of pennies to the forehead.
Hm. What's the word I'm looking for? Oh, yes:
Batman's humiliation is deliciously augmented by the fact that Robin--and a roomful of Gothamites--are watching as Batman gets pwned by a Grade Z hoodlum with some pennies and falls off a giant stamp to the hard, cold floor. Where's Vicki Vale when you need her?
Before there were blogs, there were the Gotham tabloids.
The bad guys do the logical thing, which in Gotham means "escape via the rooftops after climbing up the giant postage stamp and out the skylight." Because, you know, the rooftops are the perfect way to flee from Batman. But one of them doesn't make it, and Batman, tries desperately to salvage his self-image by intimidating a skinny gunsel. Boy, I sure hope a member of Coyne's gang isn't eavesdropping from the skylight and kidnaps the squealer....!
Uh-oh. This won't end well...
P.S. Oh, I almost forgot....!
This is what the Giant Penny does:
Small wonder that the Giant Penny is the standard by which all other Giant Props are measured. But what's it feel like to get hit by a Giant Penny? Well, we'll be discussing that later.
Batman actually uses the Giant Penny against Coyne's gang, NOT vice versa. Then it's not seen again until it shows up three years later in the original Hall of Trophies story ("The Thousand and One Trophies of Batman", Detective #158, Apr 1950).
How did Batman get his gloves on the Giant Penny? Most readers think grateful citizens just up and give Batman trophies after he saves their asses (or gets them publicity by getting pwned on the front page of Picture News). Or they think that Batman pockets trophies from crime scenes when the police aren't looking. But that's silly. Clearly, Alfred spends most of his day on Ebay on Bruce's behalf, buying up relevant giant props from previous cases. And thanks to the Gotham City Civil Code on Giant Props, the expense is actually tax-deductible.
