Life, Magnified – Blog Contest Week 4

This week’s image is here!  Good luck.

Clue #1: It circulates.

Clue #2: Double Sawbuck


6/27/2011 Image - Household, Workshop, Key Tech Item @ 90X Magnification

Dave DeMonte is the winner of this week’s post! Congrats! With impressive detail, Dave identified the image as the color-shifting ink on a US $20 bill used to print the “20″ in the lower right hand corner (see image). Clue #1 was in reference to the terminology commonly accepted when referring to active bank notes (i.e. “in circulation”), and Clue #2 is a slang term for a $20 bill. A sawbuck refers to a $10 bill in reference to the “saw” appearance of a Roman numeral X (followed by buck for dollar). Hence, a double sawbuck (XX) is used to refer to a $20… also known as a “Jackson”, “twen-spot”, or – my favorite – “double Hami” (in reference to 2x$10, which features Alexander Hamilton). In addition to “color-shifting” dyes, the U.S. Bureau of Engraving & Printing also implements custom note material, high resolution printing, watermarks, and an embedded strip that fluoresces under a black light to thwart counterfeiting efforts.  Give it a try!… the black light, not the counterfeiting.

    You know, that kind of looks like the striker area on a matchbox… But matches and match strikers within a few updates of one another?

    Is it a stitch in your “Mr. Fix It” workshop apron?

    It almost looks like some type of filter media, like for a breathing mask, but I’m not really sure.

    Up close it kind of looks like some sort of insulation or padding.

    Money, most likely lower right hand side of a newer 10 where it says 10. But i’ll go with just money.

    Clue #3: People think they never have enough of it.

    Even closer; it’s the #20 in the lower right of the corner of the $20.00 bill.

    We have a winner! Dave is correct (with impressive accuracy) that this is the color-shifting zero found in the “20″ on the bottom right corner of a US $20 bill!

    Didn’t know the U.S. government is so into glitter too. How does “workshop” in the image caption apply in this case?

    I have hidden over $2,000 cash in small bills somewhere in our workshop.

    Actually, I was trying to convey that the image is something that is everywhere. So in this case, it’s in the pockets of those who use the workshop (or, for the CE’s, it’s what’s in the hands of the ME you “charm” into making something in the workshop on your behalf).
