So I have some coins that I believe are DDO and I'm looking for the right place to post some picture to see what someone with a bit more experience thinks It doesn't look like Machine Doubling to me but a second opinion would help thank you |

 I haven't found any myself but I know what they look like with a good picture. You will Deen to post a pic of both sides of the coin and a really good shot if the area you see doubling, alit if experts on here will let you know. |

@jay, first welcome to CCF. Second, with regard to your question about where exactly to be posting images of coins that might have minting errors, here is a link to the correct subforum for US modern coins: http://goccf.com/f/5"If you climb a good tree, you get a push."

If it is on the outside edges of the devices on one side, it is probably Machine Doubling.  If the devices are reduced, it is Machine Doubling. The strike happened and the machine damaged the devices. It if a a doubled die, there should be a wider area seen on the center devices:  Note the normal image on top. Note how much wider the devices are on the lower image. That is called spread. The devices are wider than normal. So if the outside edges of devices are affected, it is likely MD.  Note on the image, the area is is flattened, removing the contour of the device. On the right you see the contour present and this is called hub doubling on the die. Thus the term doubled die die. |
