Does anyone know what these are?

[SprogletsMum]

We have found these in a box of junk that was passed on to us from an elderly relative.
Does anyone know what they are or if they're special in any way or just a bit of tat?

Looks a lot like a silver version of this. £2.50 on Amazon.

Yes it does, thank you. No unimaginable riches for us

What a shame. When I was young my Dad knocked down a garden wall between us/neighbours and discovered a batch of Roman coins. My Mum was imagining holiday homes in Mauritius and villas in Nice when my Dad proudly announced he'd handed them over to a national museum. I don't think it's coincidence that they divorced a couple of years later!
