Types You Can't Pass Up, Even If You Already Have A Few.

Capped Bust Halves - have multiples of many of the later dates.

Flying Eagle cents

...@ Spence, What are we going to do...I've got 20 to 25 rolls of those drummer boys...I just keep adding them to the bottom drawer of the dresser

Also love the wartime nickels in unc condition

Uh, if it's round, old and from the states... I'm in... :)

One could say I started collecting coins as a kid in the 90s. I kept every Bicentennial Quarter, Wheat cent, and Pre 1960s nickel I came across in change. Still have most of them from when I was a kid packed away somewhere. The Drummer Boy is such a wonderful design, and the ages of the Wheat Cents and old nickels was always fascinating.

@Joe2007 and @hfjacinto I agree the Flying Eagle cents are stunning coins. I only have a couple low grades I picked up as a newbie back in the day, but I think they are great. I understand the appeal.

@Finn235 Those Indo-Sassanian are magnificent! If one of them was an '82, I'd stop in my tracks too!

@GF, assuming you have ~900 of them, if I add my ~600, together we have cornered approximately 0.0001% of the original mintage. We are just like the Hunt brothers.

Back around 1965-1966, I couldn't pass up any pre-1965 US quarters that came my way in circulation. I managed to grab about 700 of them before they disapeared -- about 300 were dated 1964 alone.

I don't save the circulated ones that still pop up from time to time, but in mid-2009 my work got a couple solid boxes of 2009 LP2 cents and I had to get rolls of cents from the bank to swap them out as fast as I could



(This doesn't include the bag of loose coins I also salvaged.)

I got so many so fast that to this day I still haven't searched them for doubled dies

When I decided to grow my Poland collection 2 years ago, I started with an auction lot of 8 trojaks (3 groat coins) from the reign of Sigismund III. My initial goal was just one from every year 1588-1605, and covering each of the 9 mints, but most year+mint combinations (that would already be 87) also have major and minor varieties each year.
I have mostly managed to resist going down that rabbit hole, but did just broaden out the year 1598 which is the first year of using letter mint marks (4 that year, B, L, F and P) instead of a privy mark.
Still, I am looking at, and bidding on one or two of this type in every auction (unfortunately so are a lot of other collectors). Fortunately I'm not often succesful.
