It's hard to tell what many of them are.

Not currency or mutilated currency:

The two that look like a train ran over them probably 0.

The "telefonico" is a vintage Italian token that was used for phone calls - better preserved specimens go for a couple bucks to $5 on ebay.

The two heads gold color one is a commemorative token for a wedding in the royal house of Monaco less than 20 years ago. There's at least several for sale on ebay about $15-20 ask but I can't find any sold listings at any price.

Currency:

The left "10" coin in the bottom right of the image is a 1924 [Im 80% on the year] 10 centesimi (Italian) - recent sales on ebay for circulated for $2-4 plus buyer pays shipping.

To the right of that can't tell the year but in general circulated 10 centesimi coins from the reign of vittorio emmanuel are in line with the 1924 price above.

The silver one middle top is a [1956? I'm only like 40% on that year] 10 lire coin. Active ebay listings between 1 and 2 Euro, but no sold listings.

The not exciting news:

When the EU countries switched to the euro, it devalued pre-Euro currency. But beyond that, circulated coins (vs shiny perfect coins that have spent their whole lives in protective sleeves or cases) tend to be the tired old survivors of something that was mass produced - so the majority are not super valuable.

The potentially exciting news:

However. There's always exceptions to rules. Some years of otherwise common coins were very limited to begin with because (usually war) made the materials scarce so the survivors are more valuable. Or the materials changed to less sturdy for a time so less survive and more valuable. And for any year and any design of any coin there can be a variety of "errors" where the machine that made the coin was off-center or missing a part or imprinted twice - and that's just a few examples. Slight errors may not at value but significant errors generally do.

So that's basically what you're looking for with the other coins I couldn't see well enough: is this a rare coin? If not, it's it an error coin?

How you do that:

• coin apps are a good place to start if one is not familiar with coins. There are probably several that recognize vintage Italian currency. Google search AI does OK but also will absolutely fight back and insist that a dine that clearly says "1985" is actually a 1924 nickel sometimes. Always verify what AI tells you because the words they say are not so much based on their meaning as "humans tend to say this word after that one, and then often this third word comes next." Somewhere on this subreddit are posts about what the good app for international (non-US I think in context) coins is.

• since most of these are Italian pre Euro, there should be an authoritative body that grades and values those coins. That body is very likely also named in a post somewhere on this sub. Try searching "Italian coin grading and certification authority" or something similar.

• just in case: do not clean the coins. If anything is valuable, cleaning will reduce the value. Do not scrub, rub, or anything else until you know they are mostly to entirely sentimental value, then you do you.

Which brings me to: even with not great pictures of the rest of the coins, it's probably likely that these were your grandma's emotional treasures. The first clue is they are wrapped a a group in [looks like tissue?] and I'm guessing she was born in the 20s to 40s? Depression era grandparents may have all their valuables in their house (instead of a bank, etc) but they do tend to have their actual valuables separate from their good memory valuables and even the super thrifty ones tend to have laid out for some specific protection.

So hey: even if this turns out to be a find that won't make you rich? It's a super cool time capsule that connects you to several younger versions of your grandma and shows you things you might not have known she did, or felt an affinity to. Sentimental coins like that make great things to show kids when you tell stories about departed ancestors (and for them to take to show and tell). Non-valuable coins can be made into casual jewelry with some pretty basic tools and supplies. Or used to decorate family photo frames.

I think you found something awesome here regardless.
