Q: What U.S. coin currently struck by the Philadelphia Mint has never carried the "P" mint mark?
A: The Lincoln Cent.

Q: When was the first time the "P" mint mark, representing that the coin was struck by the Philadelphia Mint, ever used?
A: In 1942 the Jefferson nickel displayed the "P" mint mark for the first time ever on a U.S. coin on the reverse above the dome to denote it's 35% silver content. All silver war-time nickels minted between the last half of 1942 and until 1945 feature a large mint mark above the building's dome (except for a possible error).

Q: Other than to denote silver content, why else would the U.S. Mint use the "P" mint mark on the 1942-P Jefferson Nickel?
A: Jefferson nickels had already been struck in 1942 at the Philadelphia Mint with the previous year's copper-nickel composition. This may have also been a consideration for adding the "P" mint mark to the war-time issue five cent pieces.

Q: What is John R. Sinnock's claim to numismatic fame?
A: He designed the Roosevelt Dime. His initials, "JS", appear on the obverse below Roosevelt's bust and to the left of the date.

Q: How many sides are there to a coin?
A: Three. An important factor in deciding a coin purchase is the condition of the obverse, the reverse and the side.

Q: What regular issue U.S. coin is the only coin to feature the same U.S. President on both the obverse and reverse sides?
A: The Lincoln cent. Lincoln's portrait is on the obverse and if you look closely you will find Lincoln's image inside the Lincoln Memorial on cents minted from 1959 to date.

Q: Besides the Jefferson nickel, which other U.S. five cent piece displayed the motto "In God We Trust"?
A: The Shield nickel, minted from 1866 till 1883, is the only other U.S. five cent coin besides the Jefferson nickel to feature this motto.

Q: What is an "original roll" of coins?
A: Since coins are shipped from each U.S. Mint in large bags, there is no such thing as an "original roll" of coins. However, a bank or third party service may have wrapped rolls of uncirculated coins in paper or plastic wrappers and at times these are often referred to as an "original bank wrapped roll". Coin dealers and/or collectors are also known to put together rolls of uncirculated or Proof coins.
