1968-S lincoln 1c roll finds

[Kauaiforest]

So I was going through a older roll of 1968-S lincoln 1c coins and found 19 of the 50 coins in the roll, had this very impressive machine doubling on the date, m/m and profile. (first pic) I know its just machine doubling but its the best example I've seen and still fun to find when searching rolls.
In the same roll I found 2 different coins that had what I thought, at first glance, was the WDDR-002, but the whole right side of the building is doubled all the way down to the foundation adjacent to the designers initials. It does not have any of the die markers for the the WDDR-002. would this also be machine doubling maybe? or something else? (second pic)
Thanks

In my opinion, doubleddie.com for DDR-002 only lists the very top corner of the building as doubling and not the columns nor the base.
To me your coin looks like machine doubling.

Markers may or may not be there. They won't be there if the coin isn't a match or, the coin is a match but at a different die stage.

Markers or pick up points may be short lived and may only be on a certain die stage (or age).
Typically there are three die stages, early, medium and late, sometimes there is a very late die stage added. Those are all related to the age of the die, basically how many coins have been struck. Some Lincoln cent working dies can strike close to 1 million coins before being retired. These are steel hitting metal, they tend to wear out over time.

The working dies - the ones that have doubled dies, are made of steel and the images of the coins are pressed into steel.
Where the attributors see the doubling and show photos is likely the only places that doubling should be seen.
Since the impressions are in steel, the areas don't move locations.

Happy Hunting

Thank you!! I think that the reverse doubling might also be machine doubling as well. I looked a little closer and found on both of those coins there looks to be some machine doubling on the second "S" in States. do you think its worth sending in to the examinations side or just call it "fun finds"

The only doubled die reverses for 1968 were proof Lincolns. Most attributors use a "PR" or "P" in the designation name to identify if it is a proof, eg,
PR-1-R-I-CCW


In my opinion, if you suspect it to be machine doubling, use it as a reference coin for that year.

The way attributions work for CONECA is to create a post in the CONECA services area under attributions.
From there, they'd look at it online, and do their typical screening of the coin, but if it is machine doubling, they are not going to need to see it in hand.

The machine doubling in the 1960's and 1970's had it's dramatic moments. I too own one of them for reference:
