We have just been through this with an aunt who passed away with a collection of gold coins she wanted to go to nine nieces and nephews.

If all the coins are of equal value or all are valued based on gold or silver content, dividing them is easier. Otherwise, those based on collectors value probably should be appraised.

A dealer can give you an offer, but many of them you will find listed on Ebay--giving you a reference point.

In my aunts case, the coins were divided into 9 piles of approximate equal value--though single coins made some worth somewhat more. We then drew lots to decide who got which pile. Her jewelry was divided similarly.

The executors said the lawyer did not like the method they used, but this avoided being forced to sell everything (at dealer prices--50% off value). So some can keep them as heirlooms and for their heirs.

If you must sell yours, selling them to your siblings or other interested buyer might get you a somewhat better price than the dealer's offer. Or at least give siblings the right to match the offer to keep heirlooms in the family if you can.
