1999 P Nickel Doubling????

[Digenes]

I am trying to get a handle on this. Some Machine Doubling gets me, thinking it might be Doubled Die. Not sure if this is one of those time, though I have a funny feeling it is. Looking at the US in TRUST.

Thanks

it certainly appears to me like mdd, the pics were not a very good indicater of flatness of the doubling or not

With that much doubling you would see it on just about all of the perpheral design elements. It is machine doubling.

Thanks again all. Every little bit of knowledge I am able to retain, helps me greatly. You all have been a wealth of knowledge so far, now it is just up to me to retain it and put it into pratcical use as I go along.

Hello ALL,

Just would like to confirm that neither raised metal nor notching can be ever present in ths MDD, right? This is one very strong baseline that we have in our quest of genuine DDs.

Thank you,

Some forms of machine doubling push up a ridge of metal.

Hi Mike,

Thanks!
Whick would make the metal raised and not shelf like? Would assume there is a distinct characteristic which will definitely indicate to be MDD.

Thanks!

There are two forms of machine doubling, "push doubling" and "slide doubling". In push doubling the die "hops and drops". In other words, it hits the surface of the coin, bounces up, and lands lightly a second time in a slightly different position. This creates the marginal shelving. In slide doubling the die hits the surface and then slides laterally without any bounce. This drags the die through the newly-struck design, smearing it and piling metal up in a series of ridges.

Thanks Mike!
