<p>[QUOTE=&quot;iPen, post: 2352892, member: 69760&quot;]I hear that&#039;s at least one reason why coins are round or circular - to last much longer, which probably became standardized by convention from eons ago, then in more modern times further propagated by the vending machine industry so as to not turn back (though it&#039;s probably going to transition to more and more plastic / card based vending).</p><p><br /></p><p>Anyway, why don&#039;t they simply round out the corners to create less wear for US notes, or make the note (even slightly) oval shaped? It probably won&#039;t look as good to make it oval-shaped (at least IMHO), but what about rounded corners? Would such changes not have any significant effect to paper notes&#039; durability? And, I&#039;m sure there would be push back by the TPGs due to commercial reasons for new modern notes.</p><p><br /></p><p>Maybe the better question is, where do notes experience the greatest amount of wear, if not the corners?[/QUOTE]</p><p><br /></p>
