1980 D Quarter Error

secretsquirrel · August 10, 2003 3:05AM

I have a question about a 1980 D Quarter i have. It has a doubled UNUM and the last A in AMERICA is a filled die, as well as the D mint mark. As i live in Australia, i'm not too sure on the value of such errors on US coins. The coin would grade AU55. Any help on est value at all would be appreciated. Thanks.

The A is probably a grease-filled die, and the doubling is most likely machine doubling. Unfortunately, machine doubling carries little or no premium, and a grease-filled die would have to be very dramatic to hold much value. I'd say it's a cool coin, so just keep it

Squirrel,

What is that 50 cent scan? I spent a few years in the Alice and had the pleasure of handling a few of the Australian coinage and currency. I enjoyed the fact that the coins were being changed yearly.

oops, forgot to put which part is the filled die

The part of the A and D that are filled is actually the middle so it shouldn't be from grease as no metal flows into it. Its not the actual letters themselves, they're fine, its where the hollow in the middle where a hole should be that's filled on both.

The 50c scan is the Australian Centenary of Federation Proof 50c. Very nice coin. Alice is a nice place to visit, would like to be there now.

There's also a lot of die erosion doubling on '80-D quarters. Especially the reverse
die wasn't changed until long after its usable life.

How do those old 20P look in circulation now days? Does anyone collect them yet?

The 20cents. They have been making commemorative ones so interest in them have picked up somewhat. They are more the starting point for new collectors here, although there are some very nice varieties and errors on them just to add that bit more for the experienced collectors. Commem coins are a yearly thing now on either the 20c, 50c or $1 coins. Bit of a shame though as it's been years since we have had a standard coin proof set. 99 was the last.

Without seeing the doubling I can't say for sure what caused it but it is most likely machine doubling. As for the filling of the loops of the letters, think about the depression in the die that creates the letter on the coin. The letter itself is incuse so the area that creates the center o the loop is actually a tiny ftat topped spike of metal whose peak is at the same level as that of the field of the coin. If ths little spike breaks off (die chip) there is nothing to create that hollow in the letter and the result is a solid lump instead of a loop. These die chips normally do not commnd much if any premium.

Thanks to all for the help. It's always good to explore the other parts of the world, and it's coins. Quite often we get quarters etc in our change as i live near a major port.
