In England, if we say that someone was born with a silver spoon in their mouth, we generally infer that their wealth is inherited rather than worked for. It is not a very nice expression meant to be disparaging with the connotation that he or she is undeserving or not appreciative of their prosperity.
Collecting unusual silver spoons is entertaining and exciting. There are collector clubs all over the world for "spooners" who love to collect antique silver spoons. People such as this meet with other collectors to trade or sell as well as to share their information.
