Notice also, that the coils have legs and feet, as shown in EagleRJO's photo, above. By attaching legs and feet to the large coils, the Mint is able to move them faster and guide them more accurately than by using hoists, fork lifts, and other means. When small but very precise movements are required, the coils are placed on a quantity of trained ants who respond to verbal commands.

When time a NCLT coin or bullion piece is removed from it's original holder it is exposed to unnecessary risk of damage and surface contamination (spots). The best approach to coin conservation is to leave it in the capsule in which it came. (Yes -- I realize many enjoy paying extra money for no meaningful value.)

No. Look to the left on the truncation of the bust -- between the field and his shoulder. They are often faint or indistinct. They were added in 1918.

The presses used for .999 gold and silver were modified over a decade ago to avoid marring the delicate pure metal surface. But, once removed from the original Mint capsule, anything could happen.

You'll find Lincoln's BVDs UNDER his coat and shirt....not on his chest. "V.D.B." are the designer's initials. They stand for "Victor David Brenner." His original reverse design had "BRENNER" at the bottom reverse. The Mint engraver shortened this to V.D.B., then the Sec of Treasury got over anxious when the Washington Star newspaper claimed - with no authority - that the initials were an advertisement. (If you want all the details and photos look in my book Renaissance of American Coinage 1909-1915.)

Sure. They are also the color of pure gold, not alloyed gold. Your 0.999 bullion pieces will be AU in an instant if touched. Normal US or Sterling gold would show nothing.

Short answer - not likely. Long process, steep learning curve, bribes not accepted.

The coin is EF --- not even close to being Unc. Die cracks are common and might not be considered a die variety by VAM world people.

There are no initials on Lincoln's chest on your coin or any other Lincoln cent mad at the US Mint. After a coin leaves the Mint all kinds of things can happen -- but none of them are of any value or numismatic interest. If you can;t show the written quote from Heritage, then it does not exist as far as anyone else can know. Just some facts. We return you now to Fox "News."

Too busy....A neighbor is fighting for its life.

RE: Gold coin "softness." Experiments and controlled measurements at the Royal Mint in the 1880s established that die struck gold coins had just a hard a surface as silver, and both were a lot better than copper. (See Roberts-Chandler, et al.) Unalloyed gold and most native samples are soft, but coin gold alloy is hard and striking actually increases the surface resistance to abrasion -- that is: a struck coin's surface is harder than that of the blank planchet from which it was made. The heavier a coin and/or the greater the distance it falls from press to receiving box, the greater the number and severity of surface damage.

I was in Poland recently -- but no ANA show there.

This is entirely reasonable for $1 and $3 gold. They were in demand from jewelers, especially in Britain, for ornaments due to design, low cost, and small size. If you look in Renaissance of American Coinage 1909-1915 you can learn about the US Treasurer's private stash of these, and what was done with them.

If you're going to buy/sell coins, you must learn how to evaluate and grade coins, quickly and reliably. Join ANA and take the grading class for starters.

Photos are too fuzzy to help much. These suggest an ordinary 1880-O dollar. Better photos will help a lot.

You show a 10 Dong coin. Do you have any of the 5 Ding pieces, or the 2-1/2 Ting ?

"Are any of these worth grading?" Nope, also.

On the 50 kopek, the lighter silver coin in your 2nd image seems to be upside down. Turn it over and compare again. Since the two are different issues, I'd expect different edge lettering.

Funf Reichmark. OK...I see my mistake. I looked at incorrectly labeled pieces. The coins are 5 marks and the medals have a different rev inscription. Otherwise coin and medal are nearly identical.

Buy a master pallet and they'll give you 3% off....

I don't see anything of interest on any of those quarters. Agree they seem to be proofs.

For overall utility in striking coins steel alloys are cost effective and easy to work. Steel also adapts well to surface augmentation. Other metals and certain ceramic-metal alloys are better for certain uses.

You have no basis for your ignorant comments. Zero indictments on anything and multiple exonerations.

The piece has a 5 mark denomination on the reverse. Therefore, it is a coin and not a medal.
