Over the past several months i have run into a few coins that have grooves set within the letters. From a distance the letters and numbers look doubled but a closer look shows grooves giving the illusion of doubling.. I call them "Groovy coins". Can anyone tell me what this effect is and how it is made?
Here is a recently found penny with the grooves.
If you click on the picture you can zoom in for a better look
Thanks for your time!
