How Many Sets Or Coin Collections Do You Actively Work On?

I gave up on my Dansco US type many years ago, primarily due to changing interests and deploying capital elsewhere.

I significantly slowed my Canada type, but will pick up something at a show every couple years.

So I suppose only two (or one if I can combine two related sub-niches into a single niche).

my collection:

Type l reverse ASEs in 3 Dansco albums
Morgans in 2 Whitman albums
LWC in a Warman's folder
Type Set in a Dansco album

that's it. I have no desire to collect full (or even partial) sets of anything else. there are a lot of coins that I love the designs of, like IHC, large cents, Half Cents, capped bust halves, and more, but I just don't want a 'collection'- or 'collections'- of all that stuff. that's why I started a Type Set: so I could have one or two or three coins of those types without needing more albums or folders. so I have those 4 things going. that's enough for me. if I need to see full sets of anything I just come here and look at everyone's stuff.

i prefer a 'minimalist' approach. it fits my lifestyle (and budget).

I also started just like millions of other collectors, saving Proofs "Amarican Silver Eagle" dollars since 1986 up until I think 2012 or later..
They are all in US Mint packaging boxes.. I might re-start picking up the ones I'm missing...

I currently have way too many albums I am working on & also actively searching for coins that dont fit into said albums such as a proof Barber half dollar. But for the albums I am actively working on:
1. Intercept shield type set
2. Morgan dollar albums
3. Peace dollars
4. Commemorative type album
5. Liberty nickel album, complete but searching for upgrades
6. Buffalo nickel album
7. ASE album
8. Liberty walking half album
9. Standing quarter album
10. Mercury dime album
11. Lincoln Wheat cent album
12. Canadian type set album
13. Canadian large & small cent albums, Almost complete, just need a coin or 2 & some upgrades
13. Mexican type set album
14. Australian type set album, Not actively searching for a Melbourne centenary but would purchase one if one came up at a reasonable price
15. Philippines type set
And probably a few more that I am forgetting about Also wanting to start a Washington quarter set but that will have to wait until I cross a few of these off.

Every day, this hobby finds a new way to make me a little poorer.

Khromtau, to be honest, I'm having a little fun working on the SBA's.
Negotiating with the sellers is a bit of fun for these...
