Log a stamped bill you found, or look up one that's already on its journey.
A dollar gets stamped with DollarSpotter.com
Someone new receives that dollar, anywhere in the country
They come here, type in the serial number, and log where they found it
Every dollar bill passes through a lot of hands. DollarSpotter lets you follow one of them. Any bill works, including whatever's in your pocket right now.
Every dollar bill has a serial number printed on the front. Type that number in here, add the city you're in, and you've logged a sighting. You can do this with any bill you have on you.
When the next person enters that same serial number, their city gets added too. Over time the bill builds a real map of everywhere it's been and everyone who passed it along.
Some bills get stamped with dollarspotter.com before they go back into circulation, so whoever receives one knows they can come here and log it. Any dollar can be logged, stamped or not, but stamped dollars are more likely to be logged than nonstamped ones.
