I was thinking about my collection, coin types I like to collect and why. For those of you who don't know me that well, my collection has been all over the place - no focus. I like Morgan Dollars, Mercury Dimes and WLHs. But, I easily got distracted, and found interest in many other types over the years. So, I ended up with a mishmash of all kinds of things, with no focus and no track to completing any kind of "set". As I think about the mess I have, I'm realizing that I don't need much of my collection - that it was more of hoarding than acquisition of coins that truly make me happy. Time to reevaluate. Then, my thoughts turned to the most and least popular US coin types to collect. I'm guessing that Morgan Dollars might be one of the most popular US coin types to collect. What do you all think? What are the most popular US coin types to collect? Maybe Lincoln Cents (Wheaties and Moderns), because they are still so readily available, even in pocket change? Conversely, what are the least popular US coin types to collect? I'm thinking the SBA Dollars, maybe? But, what about older types? Barber coinage, because I've read about so many people hating the design (although, I don't understand it)? Or, 2-cent and 3-cent pieces, because people just don't know much about them? What do you all think? What are the most popular and least popular US coin types that are collected? And, why do you think so?
