I have one in just about every room in my house and one at work.
Crescent wrenches. I have at least 8 of them, of varying sizes.
Tape measures. At last count, I have 4. How many does one really need? And we keep one in a drawer in the kitchen, and, of course, that’s the one that gets used the most.
Both these terms were in NYT Connections the other day, and I haven’t looked them up to know which specific design this refers to.
do kids count? …
I mean I do kinda like them …
at least mine
4-in-screwdrivers [even though they’re now 11-in-1]. I like to leave them anywhere I might need a screwdriver, which is pretty much everywhere [I manage 10 buildings…] My partner once collected them all into one tool drawer, so we would ‘know where they were’. No blood was shed, but there were words…
Various kitchen utensils. Several frying pans of various sizes because you never know.
I got rid of most duplicated things when we moved: woodworking tools were likely the worst (best) items. Are four planes too many?
Sold my coin collection many years ago. I have three coins left (two silver Eagles and a quarter ounce mint gold coin) and will likely sell those as well.
Yes, this!
I have three active laptops representing three generations from Windows XP up to Windows 11. Technically there’s a fourth laptop in a moving box somewhere in the basement that can only run Windows 3.1. Not sure where it is or if it would even power up any more.
I have two desktop computers, fully set up and in active use. I’d have more but they take up too much space, otherwise I’d have at least four!
If I was rich and had lots of money and space I’d probably run a miniature version of Jay Leno’s Garage and keep most of my old cars, and have them all restored. Except for the two that I hated.
Things you have more than one of, just because you like them
Drinks!
N+1, buddy, n+1!
The number of bikes one wants is n+1, where n is the number one currently owns
Hi, friend & acquaintance! 
Snowshoes - (multiple) racers, old-school, & back country. I can only wear one pair at a time
Not if you’ve seen the look my wife gave me after I purchased the most recent one!
3 iPod Classics with about 40,000 songs on them. (Hang in there, buddies!)
I have two copies of The Goonies each on DVD, Blu-ray, and VHS. I’ve wanted a LaserDisc for a while, but mrs.gnu might kill me.
I have extras of a few specific spatulas in my kitchen. But there I “like them” because they’re uniquely useful to me. I’m never without even if one’s in the dishwasher.
I have 1 with a lot of old songs - so far it is hanging in there.
This is true. I’m currently looking for an old cruiser to fix up. Mrs. Jackson says I have to sell one I currently own first. Should it be the fixie or the mountain bike…?
What I’d really like is an old Newsboy frame.
What I would really like is something like a Bilenky Viewpoint. I’m taller than my wife, and my shoulders are broad enough that when we’re on the tandem, she doesn’t have a very good view of the road, which makes her feel claustrophobic. Hence, we rarely take it out for a spin. If she were in front, we’d probably ride two-up more often. And I’m ok with swapping our current tandem (a beautiful Keith Lippy custom) for a Viewpoint or similar.
Ahhh, now I understand what you meant by “(half of a) tandem”.
I have a Bike Friday triple that can be broken down/converted into a tandem so I was thinking you literally had half a tandem & someone else had the opposite half.

We’re currently doing a stand-by in a neighboring station & look what they have on the wall
I’ve had my eye on a case gong like that for some time. A 6-inch gong like that would fit in nicely with the rest of the collection. They appear on eBay from time to time, but I’m always leery about buying one lest it not work. I can usually nurse them back to health (I have an 11-inch turtle gong that’s been on my work bench for years pending a new main drive sprocket), but it’s a labor of love and I’m getting too old and lazy. It’s not like there’s a store to order parts from; these things were last manufactured in the 1960s.
Good luck at even finding someone who knows what you’re talking about if you get into repairing this stuff. There’s about 2500 hard core Gamewell guys (yes, guys, I’ve never met a woman who shows the least but of interest) in the world who share the pain. It’s a pretty small club.
When Providence got rid of their house gongs, there were a bunch of 15-inch gongs that seemed to simply vanish. The sound those made was amazing - and would wake the dead. When it was about to strike, you’d hear the hammer drop about 0.05 seconds before the “bong,” which was just enough time to mentally prepare yourself for the aural assault. I’ve wanted one of those for decades.
Porsche himself was very involved in the VW Beetle, I believe he designed the first one. Many auxiliary fittings (headlights, for example) are, at least on the older models, common to both brands.
Dictionaries.
Might have a couple of dozen.
Not 1st editions or rare examples, just classic, specialist or merely curious collections of words/terms and their meanings from standards like the Concise OED, the Macquarie Dictionary to an eclectic range such as the Chambers Science & Technology Dictionary, The Dictionary of Politics, The Dictionary of Troublesome Words, Ambrose Bierce’s The Devils Dictionary through to Douglas Adams’ Meaning of Liff.
Might even be able to produce one myself.
Cats.
Books.
