An original coin that might have missed a slightly higher grade due to the somewhat typical '21-S Obverse strike and the use of a 'woodgrain' planchet.  Very tough CAC in the grade as I have long noted that they do not like Brown Lincoln Cents, unless they have some 'pop'.  This coin shows bright flashy luster and retains maybe a quarter of the original planchet color, which is more tannish-gold than 'red', typical of period S Mints.  For reference, 104 at PCGS, 67 NGC (surprisingly low I think), versus only five CAC (July, 2025), with Zero in the new CACG holder.  Per their policy, this is guaranteed to cross to CACG at the same grade, if submitted in situ.
