Found this piece of silver in dad’s safety deposit box
My dad recently passed away and he was supposed to fly home to Thailand the very same day he died. I have a lot of unanswered questions but was wondering if this had any cultural significance — it’s a piece of silver with some tallies etched in it.
Is this purposed for a bank or a safe and to mark every time someone accesses it? Trying to understand if this was an old school cultural practice.
My dad was Lao but grew up in Nong Khai on the border near Laos/the Mekong.
Would love someone’s perspective on this.
