2001-P Sacagawea Experimental Finish?........ In A GLOBAL Slab

OAKSTAR

I don't know the difference between a normal struck Sacagawea and an Experimental Finish. I've never seen one and don't have one to compare it to. Not 100% sure of the reliability of one of these slabs.

I tried to get the right lighting, angle, reflection and texture of the surface of the coin.

Can anyone confirm or deny? Thoughts..

Add one Sacagawea dollar and some strange stuff to give it an experimental finish ................and just like that!

Yep Global slabbed a bunch of them.

It's one of those differences that the mint has never clearly defined as far as I know.

The Sacagawea Dollar has not been lacking in surprises during its existence, and this coin is no exception. These pieces were treated with an experimental rinse in an effort to to prevent the spotting that plagued the series in its infancy. Discovered in April 2001, these unprecedented pieces exhibit a beautiful golden brown color. Approximate mintage is 2,500. Here is their story.

This experimental rinse/finish attracted much attention when it was discovered on 2001-P Sacagawea Dollars. Coin World attempted to contact the Mint to get the details on this experimental process, but Mint officials refused to comment. The June 25th Issue has a detailed article on this discovery.

This discovery is also featured in Numismatic News in their June 5th Issue. They were the first to report on these experimental Sacagawea Dollars. CoinFacts.com, one of most popular online coin references, is featuring the Experimental Sacagawea Dollar as their "Coin of the Week".

I have not seen one of these 'experimental rinse' coins... or if I have, did not realize it. Probably will not command premiums and have not seen any certified by the major TPG's. Cheers, RickO

PCGS has slabbed these coins too, labeled “US Mint Experimental Rinse”. I’ve had one myself. They are more brownish in color. Last I knew they sold in the neighborhood of $75-$100 or so.

Some helpful details... http://www.smalldollars.com/dollar/add002.html
I also remember Fred W. describing them as slightly greenish if I'm remembering that correctly??

Yes, I've seen the small dollar website. I just can't tell from the pictures.

Tom, your Global Sac. Dollar is an Exp. Rinse -
but not the best example of this type.

Typically, I'd guess that at least 90% or more of them
have a 100% darker glossy 'bronze' look on their surfaces.

Yours is one of those that didn't get the 'Rinse' over all
surfaces of the coin - and my understanding is that
the rinse was similar to the annealing operation of the planchets.

The nice ones have a very special look to them; Glossy Luster
would be a good description - a darker bronze-like color.

Checking HA, I see that nice, full, glossy PCGS MS-67 pieces have
brought anywhere from $50-$85 in the past year or so.

If you want a nicer one for your collection, I'd suggest selling the
Global, (unless you like it for the holder), and buy a much better
piece, NGC or PCGS, for that price range.

Also, I estimate/guess that there were over 3,000 of them found
in the 2001-2002 period (mostly dated 2001), as I bought and
sold well over 2,200 of them from about 2001-2003 or so.

Hope this info helps.....

As reported in the Coin World article and on the link to my website that was posted above in this thread, I marketed and sold the first group of the Sac Dollars with the Exp Rinse that were discovered. Subsequently more surfaced and were sold by several other dealers.

OAKSTAR

Thanks to each of you very much! I'm glad my pictures were of the quality you could confirm and validate this coin! 👍🏻

We can put this thread to bed. Thanks again!

Yep. Here's mine. Got it for about $60 long time ago.
