Question for those knowledgeable of the Sacagawea series.

Goodacre presentation coins, I see ms68 and also SP68. Both PCGS holdered. Is the specimen designation any different than the mint state?

The early graded coins carried the MS designation. PCGS at some point started using the SP. They are one in the same.

Thank you Currin.
My Goodacre Presentation SAC is in a PCGS MS68 holder. If you look in my set it is listed as SP68.
At some point they changed the computer to default all MS coins to SP coins.
Currin is right,,,,,, MS and SP are the same on this coin.
I did not know this... Thank you @Currin... Cheers, RickO
Thanks @Currin! Went searching for the why.
Found this in Coin Facts.
Jaime Hernandez: In the year 2000, the U.S. Mint paid $5,000 to Glenna Goodacre for creating the winning design on the obverse of the Sacagawea Dollars.
The Mint struck 5,000 Sacagawea Dollars just to pay Glenna Goodacre the $5,000 commission. Mint Director Phil Dhiel delivered the 5,000 Sacagawea coins directly to Glenna Goodacre in Santa Fe, New Mexico.
Approximately five years later, it was discovered that the coins that were paid to Glenna Goodacre were struck on specially prepared planchets and by specially produced dies. As a result, the Goodacre Presentation coins displayed a different appearance that was fairly transparent. The coins struck off these dies have a burnished satin like appearance and most notable, is the fact that the coins tend to be of much higher quality than most regular circulation strike Sacagawea Dollars from the same date and mint mark.
The coins presented to Glenna Goodacre are now referred to as the Goodacre Dollars. PCGS also recognizes the special status of these coins. Goodacre Dollars certified by PCGS will receive a special designation indicating Goodacre Presentation on the holder.

Presumably same situation for 2008-W burnished buffalos
SP sounds way cooler than MS, which is probably part of the reason. They were also processed after striking, so mot mint state in the usual sense.
PCGS had an epiphany several years ago and reassessed how they designated coinage. anything out of the ordinary production realm was given the SP designator.
