A Little Family Story

Recently my mother gave me a few family items that had come back to her after a long absence. The items: a necklace, bracelet and earrings made from Dutch dimes, and two handmade dolls. They held a wonderful little family story.
The dimes- dubbeltjes- are all dated between 1930 and 1941. This was before the occupation, and they are solid silver. There were no coins minted during the war.
My grandmother had a step-cousin that had moved to the United States in the 1920's. After the war, she wanted my grandmother to send her some Dutch coins. The U.S. policies did not allow importation of foreign coins so my grandmother saved some of the first dubbeltjes that came back into circulation. She then took them to a jeweler to have the necklace, bracelet and earrings made. When new dimes finally started to be minted again, they were much smaller and not made of solid silver.
My grandmother then made two dolls, a boy and a girl. They are about 16" tall. My mother remembers her painstakingly hand-sewing the bodies and the Dutch costumes for them. My grandmother then stuffed the jewelry into the dolls' bodies and then sewed them shut. The dolls were then mailed to America.
The dolls and jewelry stayed with the step-cousin's family until they were returned to my mother a couple months ago.
Try as I might, I can't picture my grandmother doing something morally questionable let alone illegal. She was very religious and lived a very quiet life.
I guess you never know...
