From my research, I was able to determine the following retail vintage store values for your father's plates:
Bygone Traders - $36 each
Europaische Singvogel von Ursula Band - $41 each
Beauties of the Red Mansion - $39 each.
If you would like to sell close 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 - small fees - 20 cents to list plus 3.5% final price.
Another method that could be very effective would be to place a classified in the "Maine Antique Digest" It has a large readership of collectors all across the country.
I highly recommend this method. They only charge $25 for 25 words in a classified ad. This publication is a monthly newspaper as well as on their internet website.
Or try your local Craig's List.
I do not recommend eBay. It is mostly an auction/wholesale site.
A private seller to a dealer or at auction can expect 30-60% of retail value.
I hope I have helped you.
