Silver chain bracelet with silver coin charm

A post-1953 Dutch (because marked ZII) silver chain bracelet with a coin charm. The charm is a 1960 South African 1 shilling coin, which contains 50% silver. Incidentally, 1960 was the last year this design was minted: https://en.numista.com/catalogue/pieces10282.html

I bought this for 1 euro from a duo I regularly buy from. They store their jewelry in sealed plastic bags that are great to keep the pieces safe, but are terrible to catch detail through. I wasn't sure this bracelet was marked or otherwise of good quality, but I figured with a security chain, it was a safe bet. Now, I would have bought it anyway, but at purchase I did not notice the clasp needs repairing. It is no longer attached to the chain, though the security chain prevents it from getting lost. It's still wearable as is, so I'm not in a hurry to get it fixed.
