DDO Or Btp (Back To Purse)?

looks like I need to try understanding this 100000 more times

and ty for the welcome too :)

would love to see those metal flow maps :)

Here is a doubled die, that is also from a VLDS die. (Very-Late-Die-State)

Note the nice spread on the hubbing. But also note the die flow lines in that area. The die flow lines are on the fields from metal movement after several hundred thousand of strike. The wear patter is usually towards the rim in straight lines. The die had not been need a polishing (that often removes the flow lines on the fields) so there is a nice accumulation on the die, transferred as raised lines on the coins. (these lines are incuse on the die) These lines form as the die ages, kind of like wrinkles on a Senior person. LOL

On this one (also a doubled die) the lines are present, but the devices near the rim of the are starting to loose their freshness and are now rounding over a bit. Also a sign of LDS-VLDS die.

I believe this is a VLDS die, but the die flow lines were polished off and not starting to form again on the fields.

Here is another one that is not a doubled die. It looks also like the die polishing was recent on it as well.

But note the distortion of the outer edges of the devices. Another sure sign of a VLDS die.

Here is another example of a VLDS die, but it has die scratches that are present.

So it was polished and added a new set of die scratches, but the tops of the devices reveal that this is from a VLDS die.

Nickels also are a bit different.. You will often see die flow on them but also note that devices are affected as well:

Note how the tops of the devices are flowing towards the rim area and also the devices are widening a bit as well.



The new single squeeze dimes are also showing a lot of Die Deterioration as well:





After you study die wear/deterioration on dies you start to realize that as the dies age, the bloom of youth for the die is wearing away gradually. It runs through different die states that over lap each other.

I didn't have a EDS (Early-Die-State) die example when I prepared this collage. but on the EDS coins the edge of the outside deices are fresh/sharp like a brand new car rolling off the lot. As the dies age, you start to notice minor differences on the coins struck:

You can just barely see the outside edge of the device, but it is starting to roll/round over 9MDS Mid-Die-State) in the die state. The next image down you see more of this rounding over of the top edge of the coins devices that face the rim. (LDS) Late-Die-State) But on the last image you can see the distortion of the devices near the rim is more apparent. (VLDS) This actually get so bad the the fields and devices look more like a snow drift affect, rather than a shard edge between the fields and the devices:

Note on this image how the flow line flow from the field and over the devices? (note yellow lighted areas on this image) No longer is the fields and die met with a fresh line on the outline of the date devices. This is usually because of die wear, but also die abrasion can help cause this as well as the die ages over the abrasion. Hope this helps?

So what you have is a LDS/VLDS coin from a worn die. It is a spender and not a doubled die.
