It doesn’t really matter to me how the TPGs graded them. They use that SP designation inconsistently in my opinion. For example, it seems like the satin mint set coins and the 65-67 sms coins should have it...yet they don’t. My question was are the coins themselves different. It turns out they were. They used the 1964 relief.
I tend to view the “SP” designation as something the tpgs invented. They have been inconsistent in their use. For example, the matte finish Jefferson nickels from the later 1990s can be found with both designations.
Here's another random question. The Red Book lists the 2005-P mintage as 3.8 million. Does this include the 1.16 million satin finish coins issued in mint sets (meaning there was "only" 2.64 million non-satin coins) or were those figures totally separate (meaning there was 3.8 million regular finish coins and 1.16 million satin making a total mintage of 4.96 million)?
Here's a random question. I see that in 2014, they produced a "coin discovery set" for kids which included a 2014-P half with a "circulating finish," a 2014-D with a "uncirculated finish," and a 2014-S proof. My initial assumption was these coins were just regular clad normal strike coins. But, what is the "circulating" finish. Is this different in any way?
The "Circulating finish" is what is found on coin from the US Mint in rolls or bags, I will try to upload a picture of the paperwork that came with the sets.
OK, so then both the P/D coins were just normal coins pulled out of bags? Is the same true for the 2019-D rocket set?
The 2014 Discovery Coin Set contained one coin each with the US Mint different finishes. (Proof, Uncirculated and Circulated).
The description almost makes the “circulated” seem like a normal mint bag coin and the “uncirculated” sound like it was produced using specially prepared dies.
