I do too. I feel like it's an under appreciated design and most skip from seated to slq or seated to mercs. Seated to walkers.. barbers were serious work horses and I don't see many nice ones.
I'm actually working backwards from that logic lol. I've got more barber designed coins than any other (95% of them being Liberty Nickels) but I do have a barber quarter and dime. I don't have any seated but I do have walkers and one merc.
Nothing at all wrong with buying duplicates. And never forget, there are no coins exactly alike, no matter what the grade on the plastic says.
I think every purchase I've made in the last 5-6 years has been a Barber. They've been undiscovered territory for the reasons you stated. There's an article in the current BCCS journal about why it's so difficult to find nice circulated ones.
I have a small suite of Colonial and Post-Colonial coins. I just added this last night. VF-35 in an old green PCGS holder.
Beautiful peice of history. I dont yet own anything from the 1700s. I do however know what I want and they don't come cheap.
I have a Connecticut copper. My LCS has the other two but I haven't bit as they're nice and expensive. Maybe a long term lay-a-way of more than a few months,
I have a 1926 Lincoln wheat penny and it looks ro have been stuck by another coin when it was being made.
My setup is a System-3 built by Ray Parkhurst from macrocoins.com. It utilizes a DSLR- Canon Rebel T6 with a Rodenstock Rodagon D 75 mm duplicating lens. I use 3 Jansjo lamps. Lighting is everything! I really like how compactness of the system.
