I'm new to the forum in which I am hoping to get advice from you members. I started collecting coins back when I was 12 years old and stop. Now, that I am 60, and semi-retired, I am looking for a little hobby to get into that might be fun.

On that note, I was looking through some Half Dollars that I own and came across this coin that has a double image on the back side. As you can see, it also has a doubling on the feathering as well.

Any advice would be helpful....

Welcome! The doubling looks flat so I say it's Machine Doubling where the die moves a little. Not a true double die.

Well, that bites the big one! I was kind of hoping I struck it rich. I found 30 Half Dollar coins with errors. However, the majority are Machine Errors....what a sad day!

That is called Machine Doubling, does not increase the value of the coin.

Note that Machine Doubling will decrease the size of the devices and be flat and shelflike. a true Doubled Die (which does often increase the value of the coin) will increase the size of the devices.

To CCF! It's Machine Doubling unfortunately. The devices are reduced in size, and it's shelflike in appearance. http://www.error-ref.com/machine-doubling/

Single strike, damaged after the strike by die movement post strike. Happens a lot. The die is a normal die. On a doubled die, the doubling is on the die not caused during the strike. But Machine Doubling can also affect doubled dies as well, the same way.

Folks is it not ALL Machine Doubling AT THE END OF THE DAY, EVERY SINGLE ONE, EXCEPT REPUNCHED MINT MARKS?....To disqualify errors is not right....and lends to unscrupulous bargaining activity on different levels....they should ALL be qualified, graded and valued on their own level and merit

It's not an error, it's considered to be damage to the original strike. The doubling cuts into the letters reducing the width. If it were a doubled die the letters would have added thickness. The cost to have this coin graded would simply be a waste of money.

The first US coin motto was found on a 1792 half disme and read: "LIB (erty) PAR (ent) OF SCIENCE & INDUSTRY"

Sorry Nibor0313 but MD is not a doubled die.

With a doubled die, which occurs during the hubbing, the die is struck twice which produces the variety collectors look for. With MD the "doubling" is produced by mechanical issues during the strike and is not the same for each coin struck. And since value and collectibility is largely determined by scarcity, MD coins are more common. (I know I have enough 1969-S Lincoln's with MD. I want the DDO-001!)

There are some Doubled Die varieties that also exhibit MD. The MD detracts from the variety and actually lowers the value.

Some extreme examples of MD are fun to find and can carry a slight premium but generally they are not desireable.
