and the fact it is “legal currency” but not officially legal tender (even in Scotland itself), it’s weird.
The legal tender argument/debate kinda annoys me as people seem to think it has something to do with legitimacy.
“Legal tender” in England and Wales is money that the English and Welsh courts will accept in payment for debt. So the Courts said we accept money issues by the Bank of England in the follow denominations, etc.
The Scottish Courts said “we’ll accept money, or whatever we deem is acceptable to repay a debt we’ve issued” - so the legal tender definition doesn’t even mean anything in Scotland.
Keep in mind, legal tender is really specific, so if you try to dick around and pay a £1000 fine in 2p coins - it will be rejected as that is not legal tender. You can only supply certain coins up to certain amounts.
But anyway, Scottish money, or Northern Irish money is valued exactly the same as BoE issued money.
A shopkeeper being unfamiliar is fine, they should be cautious. But until they do interact with it, they’re always going to be unfamiliar.
But, this is most likely to get worse as cash becomes less common anyway.

UK here, I was definitely the last person renting in my circle, bought a house mid to late 30s. Feels like everyone else bought 10 years before.
