I have 45 elongated penny's in my collection 

Wow that is alot

Impressive!  I have 24.

nice collection I only have about 12 but then again this is not one of my main collecting fields

My elongated cents mainly focus on smashed cents in the state of Colorado; however, I have various others including older Dottie Dows.

Wow!That is alot! I only have 3!

I collect them from coin club's and coin shows when at large shows like ana where Ray Dillard is l give him a set to roll out for me 1 cent 5 cent 10 cent 25 cent 50 cent $1.00 coin 

I know Ray Dillard and enjoyed seeing him at MSNS and CSNS conventions when I lived in Michigan. Having been introduced to elongated by him, I have only been paying attention to places I actually have been. If I in a museum, I always make a couple of elongateds at their machine. The challenge is to make sure that you have older cents, pre-1982.  The copper-washed zinc cents are not going to survive because zinc is so highly reactive with the air.

IN 1893 the elongated metal rolling machine was made to produce the first cheap souvenir.it was at the Columbian Exposition I collect them as well as modern roll outs.

Does NGC or PCGS slab elongated coins? If not now, someone probably will someday. Being that they both slabbed the 2014 Baseball Hall of Fame commem's (which were concave much like elongated's), it probably wouldn't be that hard.
