LargeCents - Thanks.
I opted to collect date and mint mark in all my sets early on, and its been fun, and a challenge. I have sets in other denominations as well...cents through dollars, but the Morgans are my favorite.....guess that's pretty obvious, huh?
Your mention of your sets prompts me to reply that I, too, am trying to get my first set as close to uncirculated as I can, but it may prove to be too expensive to do on a short budget, but I do have a little set aside that I keep adding to whenever I can. When it gets built up a good bit, I go shopping.
My second and third sets consist of trickle down coins - when I'm able to upgrade a coin in the first set, the duplicate goes into the second set, and so on.
As I pointed out earlier, you can view all three sets in the members photo gallery, if you'd care to check 'em out.
