Is This 1972 Possibly A Doubled Die?

Thank you Coop. So the date is just
machine doubled also?

The 72 has such a wide spread on the doubled devices that it is unmistakable. Look at an example and you will always remember it.

When Maineman750 mentioned master die doubling, there was an issue that year that coins from all three mints were having this issue because of a doubled master die. So all three mints had this problem. They are doubled dies, but common because of the number of them. Here is what to look for on these:

But only one of the ones listed on coppercoins has the master die doubling. these are nice doubled die that are collectable. The spread is very noticeable on some and minor on others. Check coppercoins to images of these.

Most after that number are weaker and harder to find. But I wanted to show you what to look for on these. The doubling is on the die, thus the term doubled die. Machine damage happens during the strike. Because of die movement, it damages the devices with a sideways movement reducing the side of the devices. Because of this movement or bounce during the devices are usually affected part way up the device, flattening them or making them shelf like instead of rounded. Here is a close up of Machine damage:

Because of the bounce during the strike, the device is reduced by damage during the strike. this is from a normal die that altered this coin.
On a doubled die, (doubling is on the die) the devices are enlarged during the hubbing process:

On the 'B' you can see a rounded top on to top of that device. If this was MD then the color would all be the same color. But not it fades from ligher to dark. Also note the inside loop of the 'B' on the bottom. See how it is enlarged. That is because of the hubbing issue during the strike. Each strike with that die will produce the same spread. (the difference between hubbings)
Some are quite wide and the wider the more collectable the doubled die becomes:



Hope this helps.

Mdnyte...the simple answer is that your coin has both MD and master die doubling...and that is a confusing combo :)
