-that some coins are worth more than others (due to some notion of "rarity")*
* I'm not entirely convinced that every collector comprehends the difference between common, tough & rare (especially after seeing so many hyperbolic eBay listings). But I do believe that most coin collectors would have a slightly better understanding & at least appreciate what is collectible or uncommon due to condition (& what should be spent).
In my country (Spain) and I suppose that in much of Europe, many people are surprised when I look at a coin and say "it's from Andorra, I'll keep it for my swap list", and their answer is almost always "seriously are there Euro coins from Andorra? " I have commented Andorra because where I live I am close to Andorra and you can usually find coins from that country in exchange, in other places it can happen with San Marino, Monaco or Vaicano.
I also come across times that someone finds a commemorative 2 Euro coin and they tell me that they have found a "rare" coin and sometimes they ask me if it has much value.

A random non-collector: "Oh wow! Look! A coin from the 80s! How much is it worth now?"
Me: (looks at the 20 cents coin from 1986) "20 cents."
The random non-collector: "But it's from the 80s!!"
Me: "Fine! 20.0 cents."
Haha yes! I showed some friends coins and they were like: wtf is the arab numbers, then I explained the year (was a 1400 arab year coin which is 1970 or 1980 in western years) and they were all like are there other year systems?
Not sure if the following statement is still true, but many years ago, or more accurately, the 1980's, UK coinage for many years are the only issues without the country name on the coin. I was once given the reason for this, but have, due to old age, forgotten.
I would not be surprised if there are others now, but have not heard of this situation
I do remember sometimes seeing on the identifications forum there are coins
from Austria that, over 100 years ago, did not have a country on. One example ... https://en.numista.com/catalogue/pieces2082.html
"Spanish Netherlands" is not the "Little Spain" district of Amsterdam
Sierra Leone is not next to Guatemala
Belize is not a Caribbean paradisiac island for millionaires.
Aramaic dates are so abstruse that no one in Ethiopia uses them. They were only used for coins and almost no Ethiopian can understand them.
Very Good is not that great in the world of coins.
1970 is not old.
1899 is not antediluvian.
It's in great shape since its been through both wars (Yes the ISIS and Iraq campaigns must have been torture).
I love coins. Especially silver, gold and anything really old.

Only a coin collector can be able to determine the actual gregorian date of this coin :
And for the date 6537 ... I'm still looking for such a coin, for years without success
Its 2537, very easy to confuse Arabic 2 with a 6, the 2 is facing the same way as a 3.
2537 was a solar year of something related to the founding of the Archaemaenid empire of Cambyses or Darius or something like that. The Ayatollah did away with that!

You're right and I bet that only coin collectors have heard about this calendar

Hmm, why 37? It looks to me like a 36 or 34
Hi, according to persian numbers used in iranian coins, the last digit of the 1 iranian rial swown in the picture is, in my opinion, number 6 and not 7

Quote wiki :
In 1976, Shah Mohammad Reza Pahlavi changed the origin of the calendar to the beginning of Cyrus the Great's reign as its first year, rather than the Hejra of Muhammad. Overnight, the year changed from 1355 to 2535.
Then, the coin engraver on 1978 (gregorian) being not aware of this new calendar didn't understand the new date and made an error by engraving ۶۵۳۶ or ۶۵۳۷ who knows ? By the way if you find one, I'm interested
