Here are my answers; 1 1964 2¢ 2 Ben Franklin 3 I think the answer you are looking for is the 1916-D, but the most expensive sold that I know of is the 1919-D 4 silver, gold, CN on copper, and brass on copper 5 J 10 6 Chief Hollow Horn 7 1995-S silver (or 1996-S for both combined) 8 0.77344 oz. 9 Sheldon 10 C So you got #4, and #7 wrong. Technically, you also got #3 wrong.
I was confusing the Ben Franklin with a different question... Different contest... And I don't think he was wrong on number 4... 1916-d is the key to the series... He didn't ask about value... and he got the 4 types of dollar correct also... The only one that he missed was the dime mintage... The 1996-w had the lowest total mintage... The 1993-s that he listed had a lower mintage in silver only but the total mintage was between 2 and 3 million, more than the 1996-w... But Original Contest Poster will surely give the final actual answers and the reasoning for each when the contest is wrapped up...
