<p>[QUOTE=&quot;justafarmer, post: 2561563, member: 3926&quot;]No the mintmark was not being punched into working dies in 1994. For production of the US cent in 1990 the mint no longer punched the mintmark into working dies – they began punching it into the master die. This practice theoretically still provided the possibility of creating a repunched mintmark (RPM). But this anomaly would be attributed to the master die not the working die. It would not be a characteristic that could be attributed to a specific working die. An RPM attributed to a master die would produce a variety that transferred to a very large population of working dies. Many many working dies would produce this same RPM. If only one master die was utilized for coin production that year then all the coins produced would exhibit this same RPM. If three different master dies were used for die production in that year then approximately one in three coins produced that year would exhibit the same RPM.</p><p><br /></p><p>After 1994 the Mint added the mintmark to the coin design – therefore the mintmark became a design device engraved into the masters, no longer punched, – the same as any other design device and therefore only subject to producing a doubled die characteristic.[/QUOTE]</p><p><br /></p>
