1991 Lincoln Penny Doubling

@ros, to help us out a little bit, can you please tell us which design elements seem to be doubled with this coin hand? Thx.

From what I can see, this looks like Machine Doubling. Better photos ( closeups) would help.

I also have a 91p penny of this type DDR. I found it a couple nights ago penny foll searching. Reverse doubling. At the end of the month. I'm going to get more equipment for my new found hobby of PSerching. Then, I can post photos and communicate better. I'm on ps4 now. I have only searched 4, 25 dollar penny boxes so far. I keep a Canada jar going, also I keep a possible error jar going, so that I can scrutinise these at my leisure. Another jar I keep is the shiny jar, any shiny copper goes there, for futher scrutiney at my leisure. Oh and ya I keep the wheaty jar going too. Also the jar which I put pennys to be rerolled and sent back jar(those with no value to collectors. I am also rerolling searched coppers and am rerolling them all, same dates to the roll. So I did 10000 pennies in a month. So I think I can search 100000 a year. I believe it will be profitable in the end. It already is slightly profitable. I hope that when I'm done collecting in 2030 or so, that Pennies will be no longer minted, thus possibly enhancing any value.
