Please explain the method of applying the "rolled edge" to the 1907 eagle $10 gold coins?
The coins have a beveled edge, rather than the square cornered edge with wire rim found on other gold coins. The difference is due only to the different shape of the die surface. "Rolled" is a misnomer, although over the years many attempts have been made to alter (other denomination) coins by actually rolling them through a die to round the edge.
Is there a half eagle variety similar to the 1922-D "No D" cent?
Examples of 1916-S half eagles exist that do not have a mintmark. So far as I know it has never been determined whether this was due to a filled die, or if they were struck with a die without a mintmark like the recent proof coins.
Just how rare is the 1916-D dime with repunched mintmark?
As with almost any minting variety, there are no exact numbers to work with, so estimates have to be made based on the numbers that are reported in the hobby. In this case we do know that there are two dies with repunched mintmarks for 1916-D dimes, and that there are four different reverse dies in all that have been identified. So in theory, half of the 1916-D dimes should show the repunch. Since the 1916-D dime is in itself a rarity, the two varieties with repunched mintmarks are just that much rarer.
I have several coins that I bought several years ago that have tilted mintmarks, and some are out of the normal position (low and high, etc.) Are they worth more today?
Unless you paid face value for them, they are probably worth less, as minor tilts and mintmark locations are too common to have any collector value. If the mintmark is tilted more than 45 degrees, repunched, or touching some other part of the design, then the collectors will be interested.
Is the 1942/1941-D dime from the same hub as the 1942/1941(-P) overdate?
Two hubs were used to produce this overdate, one with the 1941 date for the first impression, and a hub dated 1942 for the second impression. However, at least one of the hubs was not the same for the Denver die, since the positioning of the overdate is different than it is on the Philadelphia die.
When was the 1880/79-CC dollar variety first reported?
If my records are correct, it was first brought to public attention in 1965. There are several different dies with overdates for this date and mint. Veteran dealer Harry Forman reportedly discovered the overdate in 1964. Since then several dies for the date have been identified as overdates.
