In the antiques world, an item is not an "antique" unless it is over 100 years old.
Your 1975 set is considered "vintage" as it is only 41 years old.
As a vintage, hand painted, 10 piece, boxed Chinese tea set, it has a retail value of $110-130 assuming good condition.
The peach blossom is traditionally a sign of good luck to the Chinese.
If you would like to sell your set, the internet gives you the largest pool of buyers.
Online auctions such as eBay usually result in values lower than retail.
Try the site etsy.com. It charges only 20 cents to list and 3.5% of the final sale.
A private seller to a dealer or at auction can expect 30-60% of retail value.
