Do You Collect Coins In Series?

I generally do a series for modern coins, but if I really like something Ill get it which will usually lead to a full series or date set series in the future

I am currently one coin away from a complete Morgan Date Set in AU-BU (missing 1895), and a couple coins away from a complete French Overseas Territories aluminum 1 Franc set. Also working on a BU 46-64 Roosevelt dime set and a complete Lincoln Cent set. Other than that I collect whatever comes my way

I try to get some series, but not much, and I certainly won't be hunting each year... especially where I have no chance to anyway (I might only have 22 dates to go for a Wheat cent date set, but I know that I'd never get an 1922-D unless I search for it on ebay - and 1915, 1921 and 1931-33 would also be tricky). In fact, the only types I'm currently collecting as a series are circulating coins of my own country, and even then I'm sticking to getting them from circulation... so I had to wait several years for an 1999 copeck - they never really circulated much, and 1999 is a much less common date - and I'm still missing many dates from SP mint because they're much less common in Moscow!
And strictly only collecting a single type? Like, seriously? I fail to see how anyone could possibly restrict themselves so much (well, unless it's a really varied type - like some ancient Roman ones - in which case they'd have no chance to get anywhere near a full set).

I'm collecting all denominations, all possible years of all US coins. Possibly the only coin I'm not interested in lately is the Liberty Head Nickel. Otherwise whatever I see that I like.

Definitely not series collecting for me - sounds dreadfully dull :)

I m collecting a date-set but I know I'm in way over my head on prices for some of the dates.

I collect world coins by type and don't care about dates. There are some exceptions which are interesting in other way like dots after date (Canada) or different fonts and surroundings. When collecting by types there are usually cheap dates in different series to acquire - no worry about rare dates!

Boy ima all over the place. Mind u, my interest in coins is solely silver and gold proofs, starting at 1 oz and I;ll do the fractionals as well.

I been trying to stick with certain governments. Now granted some may say how boring, like if you are buying proof gold eagles, well all that changes is the year lol. Same with Silver Eagles

But, like say, Mexico Libertads... they have fractionals. I have skipped the fractional pieces and instead only stuck with the 1 oz proof. The silver Britannia's also come in fractionals via their proof set. Now there I would make an exception and am now leaning at collecting besides the BU and proof Britannia, getting the annual proof silver set, even tho 99% of my 1 oz silver coins are either BU or Proof.

So I mean ima all over the place.. I wanna stay with a series and type.. but I have decided that I want to be flexible.

Same thing happened to me with the China panda silver. I cant get a proof each year of a Panda, because a 1 oz proof panda doesn't exist for every year with the same image as the BU version. Sure, they might release a medal (proof) and they have a 5 oz proof but there's no issue of a proof version of their BU panda 1 oz silver coin.

So, as a compromise, I am going to get a sheet of Pandas since I cant get a nice 1 oz proof :D I know it sounds weird but I do this with my collection to keep things flexible and varied. :D
