Honestly surprised no one here knows of or mentioned shmires ..
I just the last month got really into shmires judaica research
https://jgreenstein.com/061-a-rare-silver-shmirot-kiddush-cup/ http://cja.huji.ac.il/browser.php?mode=set&id=260https://images.app.goo.gl/eXqZSVyazBeG22Vr6A chasid would give the Rebbe a kvitel and money as a pidyon. The Rebbe would give back a coin to chasid as a shmire.
When the chasid had enough coins, he would make a becher sometimes.
There are hundreds of known instances.. probably existed in tens of thousands...
Some made spoons etc
What I find interesting is that a lot of them are not identified who it's from so I wonder if it's just a mixture of stuff or they just didn't bother?
One becher says "rabeinu hakadosh m'sadigur" but doesn't mention which.. making me wonder if maybe it was a combination of a Few.
Btw regarding shmires and judaica, hamodia had an interview with the imrei chaim of vishnitz grandson
He said at the Seder by his grandfather, there was someone trisk? From London. .
The imrei chaim approached him and asked if he could switch kiddush cups with him for Seder.
Trisk's cup it turns out, was made from shmires of various Rebbe's.
Interesting that this was something not just chasidim did but the Rebbe's also looked to
