Welcome to Just Answer and thanks for your question. Gorham made the Buttercup pattern in just about every possible utensil there is. What it is worth depends on quality. Second hand retail for "excellent condition" pieces is about $375 per place setting. There are several varieties of butter spreaders going from about $35 to $60 depending on whether they are hollow handle or flat handled. Likewise, they make several cake cutters and servers that range from $50-80. Of course, those are retail prices. You will find prices on ebay and elsewhere as little as 50% of the retail.
