They wanted a declaration of an individual item that was worth more than £10k, £2500 for jewelry. He would not consider the Pins as antiques or art.
Renewal time is soon so I will ask the questions again though I don't quite think my collection tops £10k or comes close but if they did replace the three with AC/DC and a Metallica I would just play those two until I got bored and then swap them for another TAF, IJ and
CFTBL.

I do consider them as part of the total sum insured and make sure that they are covered in that. I see there being two main threats to my collection, house fire (caused a pin or otherwise), an attempted theft ends up with a trashed backbox, wedged in the kitchen door way. The first situation they are covered, in the second situation I could repair them if the Wife didn't then kill me.
