Turning Coin Into Jewelry?

Often it is more expensive to have a jeweller use your materials than to just buy a new item and keep your materials.

To make an item yourself without a set of mills, swayges and other specialised items is not ideal but is posible. One technique that could be done is "cuttlefish casting"

First you put some saw marks around the edge of a piece of cuttlefish before cutting it in half. Then an object can be squeezed between the two halfs to leave an impression (something like a wedding ring perhaps)

The object is removed and a channel is carved out from the impression to the edge in both halfs. Then the two halfs are put back together again (align the saw marks on the edge and tie together with steel wire)

Now you can melt your coins and pour into the hole that channels the material into the impression, you will need to get the metal very hot.

What will come out of the cuttlefish is a crude casting that will need to be cleaned up considerably with a file and emery papers but it can form a basic ring or crucifix or other simple designs.
