Hello, me again with another question...

Have had a quick search through old posts but am still a bit confused (easily done)

I've got plans to make some bangles that will need hallmarking. They are silver and bronze, and the silver part will be over the 7.78g limit. I'm under the impression that they need to go on a seperate hallnote to my other silver things, but I don't know whether that means I have to pay a seperate minimum charge with it being a seperate hallnote?

I'm really hoping not because I was only planning on making a few and it's going to make them end up being so expensive it won't be worth it.
