Have you ever heard of the word guppence?

[TilerSwift]

During a conversation with my neighbour I used the word guppence (possible misspelling) to refer to a trivial, piddling amount of money and he remarked he hadn’t heard that word since the early 80’s and we both clearly understood what it meant.
The thing is we then googled it, as you do, and Google has no record of it!.
We have since canvassed various people, who have never heard of it and agree can find no trace of it on search engines.
So this word is either of exceptionally local dialect or we’ve got one up on the font of all knowledge that is google?
iabu - never heard of it
ianbu - yes heard of it

I’ve never heard of it. I think if your neighbour knew it too the only explanation is that it’s an extremely local dialect.

If it's not on the Internet then I reckon it's just the people in that pub that used it.
