Handarbeit Porcelain and Gold Tea Set

I have a Handarbeit tea set made of porcelain and 22kt gold, it was purchased in Germany about 30yrs ago, it has the teapot, creamer, sugar dish, 6 plates, 5 tea cups and 5 saucers. I have no idea on the worth, it was left behind as part of an estate. I offered to sell off many items for my friends who live in another province and didnt have the time or means to take care of many of their mothers estate items. If anyone has any information on the set and specifically what it may be worth, I am looking to sell to pass on the funds. Thank you in advance.
