what do you call this?

Coin purse

In UK that's just a purse.

I'd say a coin purse.

Coin purse (USA). Change purse/pouch would be unusual to me. Might be more common in another country

As an American, I’d call it a coin purse. Not sure what British English would call it but I’m pretty sure “coin purse” is actually one of those instances where the British called it a coin purse and the Americans never changed the word. After a little search, it seems like some places would just call this a “purse” but if you were to call this a “purse” in the United States you’d get a weird look as typically the common word for “purse” in the USA refers to a woman’s handbag, where you’d keep wallets, phones, and some would keep a “coin purse” inside their “purse”

A clasp coin purse

Coin purse or change pouch

In American English, those are clasp coin purses. A coin purse is a small, sealable bag used specifically for carrying coins (and possibly other types of money). There are several different designs available. Colorful clasp coin purses like those shown here are typically carried by women within their larger handbags or purses, as we call them. In most other varieties of English, those would simply be called purses. Purses by default are small bags for carrying money. A large handbag that holds numerous items would not be called a purse.

I'd call them purses with change in them.

Purse (gb)

coin purse

I'm in Canada and would call it a change purse. If I heard coin purse, I would know that it meant the same thing, but it's not my default label for it. If I heard wallet, it would be bigger and have room for paper/plastic money and credit/debit/gift cards. If I heard purse, I would automatically think much bigger, room for a wallet, phone, makeup, etc with pockets and zippers, and a strap. And a clutch is a small purse, that can usually be held in your hand, but also sometimes has a strap. To me, a handbag is an old lady way of saying purse. LOL.

“One of those old-lady, little coin purses.” I’m not trying to be a smartass. It’s just, if you’re like me, keep in mind it is also OK to just describe what you mean instead of having the exact term. People will still understand you, and native speakers do it all the time.

Coin Purse

I'd call them purses.

In British English a small item like this is a purse, and I've never heard the phrase 'coin purse'. (I presume this is because in US English 'purse' can mean a much bigger item that we would call a handbag.)
