Why do coupons have a cash value of ';1/100th of a cent'; or something similar written on the back?

I'm guessing this is a measure to avoid some sort of liability... but why?Why do coupons have a cash value of ';1/100th of a cent'; or something similar written on the back?
Exactly, they have a miniscule cash value so that people don't try to use them as money. Stores redeeming coupons from the manufacturer's have to be prepared to show evidence that they actually sold as much of the product as the are redeeming.Why do coupons have a cash value of ';1/100th of a cent'; or something similar written on the back?
so u can`t sell them after they have expired
It's to keep you from collecting and cashing in the coupons, to trade for cash, instead of the merchandice they were made for.
Collect one hundred them, and cash them in for a penny. 1,000 of them, for a dollar. Cash in at the manufacturer.
Because the federal government has decreed that coupons be counted as ';currency'; for purposes of accounting. In other words as currency a single coupon is worth 1/100 of a penny. You could buy 100 of them for a cent. Thereby giving them value of 1/100 of a cent.
A coupon can be redeemed for cash by law


to keep people from doing just that the issuer sets a value


so it would take 100 coupons to get a penny.


People go nuts with misprints
I'm thinking stores don't want people coming in and demanding money ($1.00, .50, etc...) for the coupon, even though they're not buying the product.
No clue, I'm marking this question so I can come back and read it later. Death to infidels!
Because you would have bums and crack heads trying to collect and cash them in for 5 bucks.
so what is the point of writing that the coupons have any cash value. Leave them as coupons only with no value that way even if you have a million you wont be able to get nothing :) am I right ?
