Why did the U.S. government put grooves on coins?


If each currency note printed in the U.S. were laid end to end, approximately how many times would the

Got Chapped Lips? I got the solution from Mary Kay Satin Lips Set.  This set includes a Lip Mask and Lip Balm. It will make you lips soft and kissable.

Got Puffy eyes? Then Indulge Soothing Eye Mask is the
answer.  Put it in the refrigerator for  cooling
relief to your puffy eyes. Please look at my website www.marykay.com/terricrippin for all your beauty needs.

g. Why did the U.S. government put grooves on coins?
So that no one could shave the edges. People often did this when the coins were still made from silver
and gold. Now each coin has a distinctive groove pattern to help visually-impaired people tell them
apart.
