<p>[QUOTE="Stl Coin, post: 6686511, member: 119062"]I am well versed in the minting process as well as the difference in MD & DD technical processes. I have managed to acquire several excellent BU examples of the 2000-P Sacagawea $1 over the years that possess a very distinct, interesting & repetitive anomaly that appears to favor a DD. Jean Baptiste <Sacagaweas baby> has 2 sets of eyes, 2 noses and 4 lips. Sacagawea has 4 eyes/pupils and 2 chins, in 2 examples there is very light South & West shelving on the date and legend ALTHOUGH the detail "doubling" is strictly North & South. 2 different examples have the same detail "doubling" without any date/legend shelving. Finally 1 example displays defined tripling of details sans any date/legend shelving. All specimens show no die misalignment throughout the planchet usually seen as a co-centric circle around the outer edge appearing as a lighter "inner" rim. I have a working theory that each specimen are actually closer to a multiple strike caused by what's known as "Ejection Doubling" which is caused by a combination of a loose collar under excessive strike pressure and press speed. This would explain both the Doubling, Tripling & Shelving. Back in 2005, I brought this to the attention of J.T Stanton <Cherrypickers Guide Author>, in a well stated manner, J.T agreed with my theory but stated that technically it is a Multiple Strike, but is a type of error that cannot be traditionally traced down by Mint records therefore can't be identified as an traditional error. He did however agreed it is a legitimate Multi Strike Error because multiple specimens could be identified within the minting process. I will shoot some pictures and post the variants. I believe one day these should be certifiable as such. Happy Collecting![/QUOTE]</p><p><br /></p>
