A Collector
It's amazing how we all have differing scales.
Using Moneytane's photos, I'd have considered everything up to & including the 1860 penny as “worn” - varying degrees of course, but worn nonetheless. I wouldn't turn down coins in that condition if I didn't have them, but I'd always be seeking to upgrade.
The 1911 florin I would only consider as “fair”; virtually all the design elements finer detail has gone but it is immediately identifiable, and the deeper detail very much present.
The Parliament florin I would consider “good”; a reasonable amount of fine detail is still there, but a lot has still been lost too.
The 1944 florin would be “very good” as most of the finer detail (feathers, claws, King's hair etc) are there. A couple of minor circulation knocks.
The 1934 florin (a gorgeous coin btw) would be “fine” or “extremely good”. The finest detail (King's moustache hairs, crown, eyes) are very well distinguished.
The 2023 dollar, assuming it was pulled from circulation, would be my “very fine”.
But I appreciate my era of core collection (1968 to present UK circulating coins) is much more recent & thus more higher grade circulation coins still exist. So I'm judging Moneytane's older coins by my modern coin standards.
I imagine if I had to revise my scale for older coins, I would be more generous with the “acceptable” amount of loss to allow for the greater amount of time passed.
P.s. thanks to Moneytane for taking the time to take photos of his each grade. 🙂
I want to see your scale.
PS want to tell the US mint, that their Uncirculated strike coin, that has never been touched by human hands and was struck 3 times, is only Very Fine. There is strict grading and then there is being on another planet.

I call this a proof, you would call it around “Oh thats very good, maybe even pressing fine, very dirty though, its not gleaming”
What is “extremely good” - that grade does not exist on any scale I know.
I mean would your UNC be MS70 or 100 and then EF is MS69, VF is MS67.
I actually think my grades are very strict. The American 1872 dime is probably barely Fine in British money. And it shows wear heavier on its tails side.
The 1944 Florin, does look nice, but on George the hair strands are barely visible and face,cheek etc nearly all blended. Like a lot of coins, I suspect this coin was cleaned in the past. A lot of VF to EF early NZ silver can appear UNC to the uninitiated and the Tails sides had higher rims, meaning coins at VF have basically all the detail. The monarch side is really where you grade for coins VF and better.
I use the Australian/NZ system which is British standards, but the Grades Very Good and Good are equivalent to British Fair, where as our Fair is like that 1688 Reiderschilling I showed.
Not getting at you, but the post was a bit mean spirited and kind of rubbished my opinions.
Those coins sum up the difficulty of unifying grades. Actually finding photos of coins at various grades was hard enough, as very few coins slip nicely to exact grading standards. Plus we have the problem with coins of uneven wear, where one side has heavier wear due to more use or higher relief detail which wears quicker. Then you have cleaning which can make a worn coin look better and everything else.
Pretty much all the coins under VG were cheap and mainly parts of big accumulations, and photos from when I started collecting again in 2019/2020, when I was a less seasoned collector. The later photos are mostly coins I have bought in the past 2 years.
Most collectors will have more coins grading, about, nice, good, almost and near, a grade rather than exact grades. I may have 10 VF coins and 10 EF coins, but I will have 37 coins that grade goodVF and 5 that grade gVF/aEf etc.
I love coins. Especially silver, gold and anything really old.
