Yes, with approximately 50% of the coins on each type. This is because the edge lettering is done first, then the coins are put into the line to have the obverse and reverse put on it. They do not try to have the edge lettering one way or another. The presidential coins are the same way. the only exception is with proof coins in which they make the edge readable when looking at the obverse. If you find a type B proof coin, then you have something.
According to Ron Guth from the PCGS Library, the edge lettering is done last. http://www.pcgs.com/articles/article_view.chtml?artid=4911&universeid=313&type=1 David Camire from NGC says the same thing: http://www.ngccoin.com/news/viewarticle.aspx?IDArticle=459
I didn't know there were two different types of native american dollars. Dansco only has one in there book. Please explain. Thankyou
The "Type" specifically relates to the orientation of the Edge Lettering. Type A would be where the lettering reads normally when the Obverse of the coin is facing up (i.e. The Indian Lady Planting the Corn) Type B would be where the edge lettering reads normally with the Sacagawea Side up. This is according to PCGS's definitions.
Whether the edge is put on first or last is actually moot, the point is they don't try to make them all one way or the other so approximately 1/2 will be A and 1/2 will be 2 (or 1 and 2 if you prefer). The real error is to find a proof with the edge lettering in position 2.
Type B is with the edge right side up when your looking at the obv. A type A proof would be the unusual one. That would be Type A, but the indian planting corn is the reverse not the obverse.
