Does anyone know about selling vintage jewellery?

[Overreactionpossibly]

I was just about to list a bundle of old silver rings on eBay and noticed a markers mark
N.E. From Denmark inside one of the amber rings.
Googling the mark it is made by Neils Erik in the 1960's and could be worth a little bit (not a huge amount but more than the £10 staring bid that I was going to put all of the rings on eBay at).
I don't know where to start with selling. Am I best to put it on eBay with the details or to contact a jeweller? Or something else?

Hany help would be fabulous. Thank you

Shamelessly bumping but also wondering if anyone knows what ALP stamped inside a piece of old silver coloured jewellery means please?

Take it to a reputable independent jeweller and ask for an insurance valuation. I did this for a ring which I thought had a crystal & it turned out to be a sapphire! So obviously a lot more than I originally thought it was.

It might be worth taking it to an antiques dealer (either at an antiques fair or at a shop) that specialises in jewellery.
It's worth noting that they will give you a lower price if you are selling to them compared with a valuation.

Thank you. I think that it's worth a out £100 so nothing major, it's from the 60s so not all that old. I just wasn't sure what the best option was.
