Your set of 16 place settings of Golden Posy by Alfred Meakin has a current retail vintage store value of $1540-1640.
The 22kt gold trim adds little to value as gold is too hard to extract from porcelain. It just adds beauty to your set.
As for where to sell.....If you want to sell quickly at wholesale prices, try one of these sites.
I do not know where you live so I will make suggestions for three countries.
If you would like to sell closer to retail , some ideas are:
The internet has your largest audience of buyers. Place small ads on these sites or set up your own small store on these sites.
Etsy.com - no or small fees
Goantiques.com - more upscale fee based
Rubylane.com - more upscale fee based
Amazon Marketplace: http://services.amazon.com/content/sell-on-amazon.htm/ref=footer_soa?ld=AZFSSOA
A private seller to a dealer can expect 30-60% of retail value.
