Jyoto China company were Japanese exporters from 1934-1976.
My research and calculations indicate an estimated retail price of $480-580 assuming only 6 good cups and no other chipping and depending on sale location.
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.
Online auctions like eBay generally bring wholesale selling prices.
If you would like to sell close to estimated 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 - small fees - 20 cents to list plus 3.5% final price.
Amazon Marketplace: http://services.amazon.com/content/sell-on-amazon.htm/ref=footer_soa?ld=AZFSSOA
Or your nearest CraigsList.com where you can list items for free.
How to pack and send china:
China is best packed with 2 paper plates between the plates, platters and saucers. Then wrap a few plates together with several layers of bubble wrap. Tape the loose ends of the bubble wrap together.
For cups and bowls, wrap separately with a couple of layers of bubble wrap.
Put a several inch layer of crunched newspaper in the bottom of each packing box.
Arrange the heavier items on the newspaper first. Then add the cups and small bowls on top of the heavier pieces.
In a second box, crunched newspaper, stacked plates face up, not on edges followed by lighter items.
Before putting the newspaper in the bottoms, reinforce the bottom and sides of a strong corrugated box with cut corrugated sheets (cut from another box). Then start with the crunched newsprint.
After filling each box up to about 5 inches from the top, put several inches of crunched newsprint on the top of the stacked china.
Firmly tape the box closed with several layers of tape.
Write two things on all the sides of the boxes - "Fragile" and "Top" with arrows pointing to the top.
On the top, write "This side up."
For expensive items, the Postal service will allow one to purchase higher insurance.
If possible, ship two-day service. This eliminates long trips with boxes transferred from truck to truck.
In general, a private seller to a dealer or at auction can expect 30-60% of estimated retail value.
Insurance replacement values are usually about 10% more than retail values.
