<p>[QUOTE=&quot;GDJMSP, post: 290818, member: 112&quot;]Method for application of the mint mark to Proof coin dies was changed in &#039;85. It didn&#039;t change for circulation coinage until &#039;90 &amp; &#039;91 - page 20 of the 2007 Red Book. Pretty sure cents were the first to be changed and halves the last.[/QUOTE]</p><p><br /></p>
