SMS coins don't have mintmarks.

 

Nethier do buiness strikes

 

Not necessarily true.

 

1965-1967 do not have mintmarks, and SMS were made 1965-1967. Lets see your 1966-d Quarter.

 

Your statement was, neither do business strikes.

No year mentioned in your post, and to that I stated not necessarily true.

Of course there are no mintmarked coins from 65-67, anyone knows that.

 

BU,

SMS sets were made 1965-1967. During those years the Mint did not use mintmarks on any coins.

 

Anyways lets get back to the question.

 

Eric, SMS coins are somewhere between Business Strike and Proof. Business Strike coins are struck once under normal pressure on normal planchets using normal dies. Proof Coins are struck twice (or more) under higher pressure on specially-prepared planchets using highly-polished dies. SMS coins were struck once under higher pressure (but less pressure than for Proof coins) on normal planchets using polished dies.

In general, an SMS coin will be better-struck than a Business Strike coin and will have semi-Prooflike surfaces.

 

That sounds like mine, thanks got it for MS price

 

This is a good post, would be great with pictures.

 

for sets what you said is true, however I have seen 2005 -2009 SMS cents on some graded cents

 

Is satin finish the same as the 1965-67 SMS coins??

 

In general yes, but a quality business strike can't always be told from a lower end SMS coin.

No.

The problem was that once the mint started putting out coins that didn't fit into the regular catagories of Business Strike or Proof they didn't know how to label them. So some were called Matte Proof, some were called Specimen, and sometimes they just labeled them as SMS meaning they came from "Special" Mint Sets (more properly Special Sets from the Mint). Then the satin finish pieces came along and by now all labeling is up in the air witht he satin finish coins sometimes being called Satin Finish and some times being labeled SMS.

 

This may help in 1967 there was a Philly roll Kennedy & the 1967SMS set
here a photo of each.

 

I've clearly stated that.

 

My grandparent owned Tanner Bank in Catskill NY that were I got the non SMS roll.SMS half were struck with highly polished proof like die in 65&66.there was an hole set of article 1950-2000 that Coin World devoted to the 1960's.they stated that 90% of the 1966SMS were struck in Denver????
but there was Bu roll banks had to order that how I got my roll of non SMS 1967 Kennedy.
My grandmother gave me the roll & a Box of 10+1967SMS set for Xmas 1967

 

Any possibility your grandparents would be interested in adopting a 63 year old grandson? I don't have any grandparents and desperately need some.

 

Well, outside of what has already been said the 65-67 SMS do come in a hard case from the US mint. Unfortunatly these are easy to open and close up. But they will be of a higher quality. They were pressed 2x on cleaned dies.
