Post your Lincolns!

Is it just me, or has Lincoln gotten up from his chair and turned around on the reverse?

Sure does!

 

Can anybody help me with this one and tell me if they see any doubling in this coin please and thanks.

 

1982 small date zinc

 

1982-D Large Date zinc

 

That pic isn't very clear but what I see is machine doubling notice the flatness almost shelf like. I will defer to an expert but I say no.

 

Found this 79-D a while back, messing around with a few things today. Sorry for the crummy pics, these are defiantly not the best I have done in a long time.

 

2009 FY Lincoln 1c 1DR-027 Proof Like

 

I bought a wheat cent bag for $3.00 and out of this bag I picked this beauty, 1958-D 1MM-021 D/D/D/D/D W, NW, & SW & SW. She is worth more that $3.00 Its raw but I would appreciate an estimated grade if anyone is comfortable with it. Again my apologies for the images, I have been using my iPhone and a lens magnifier.

 

The off-center punch in post #3362 shows what the planchet looks like before it is struck. I can visualize how the lines on the raw planchet can affect the strike of the coin. Depending on their intensity and whether they represent poorly mixed alloys, these lines could affect the coin with anything from lamination problems, to woody coloring, to linear patterns that show up in toning.

Just some random thoughts...

 

Yes, when Zincoln is not struck with sufficient pressure, you can see those lines on the design high points. If you dig, you can probably find some past discussion on "planchet lines". Here is a greaser I found - it was an excellent conversation piece. The lines give a nice look at the planchet characteristics:



I don't believe there are any alloy issues with Memorial cents. The memorial woodies are more like planchet impurities and none of them resembles anything like those from the 1920's.

I believe the Memorial "woody" lines are from worn rollers in the planchet sheet rolling machines. It is my theory the rolling fluid used when making the sheets was garbage - full of suspended solids. As the machine rolled the sheets, the fine impurities got embedded into the rollers, damaged them and this gunk transferred into the planchets. Sheets are rolled through different levels back and forth until the desired thickness is obtained. The gunk stuck in the rollers impregnates the surface forming lines.

As I recall @Doug stripped a one sided woody and you could still see faint traces of the lines? This implies it has depth, but not to the extent of a "improper alloy".

Happy 4th of July!

 

Great information! Amazing that your coin has full steps on the back and is so weak on the front.

 

anybody know of this is a rpm or a pmd?

 

PMD Looks like a stain or corrosion of some type.

 

Thank you much appreciated!

 

Here's a nice trio of Lincolns I imaged this afternoon:
