Have you ever used google AI lens? You know the tool who gives you sauce on your pics.
Well, it made my job 70% more efficient.
I chase after rare coins for a living. For pseudo-recent coinage (1600-2000), it's quite easy to figure out enough infos on the coin and find back what coin it is, especially if you are used to it.
When it becomes tricking is when you go deep into medieval era/feudal age/archbishopries or antique coinage. For example, just in the duchy of Bavaria you got hundreds, if not thousands, of different billion pfennigs over the centuries during the middle age, all minted in countless locations, all under different rulers. No date, no location, no weight, no composition, no ruler, NOTHING written on them to indicate anything, just some drunkard monk's doddle. Often on very beaten up coins from 800 years ago.

Do you know how many dusty docs, old pdf grimoires specialized in esoteric coinage in german, etc.. i burned my eyes on to find one fucking stupid tiny coin?
And imagine this but thrice as painful when it comes to ancient arabic coinage.

Now i screencap, ctrl+P on jewgle and within 2sec i have a result. It's not always accurate, sometimes your coin is so rare it's not even accounted for anywhere, but 99% of the time it will shart a result close enough for you to figure out precisely what it is. AI is making wonders for me.

But one example is often better than a long discourse. See this pic? Try to figure out what it is without using google lens/any AI.
I'll give you the basic infos :

I could take months before you find an answer all by yourself as a neophyte.
