Hello and welcome! My name is Doris.I have been an antiques collector, dealer and appraiser for over 56 years.I will be pleased to help you.
I researched your question before I decided to answer.
I found where a set of 23K Tutankhamun Exhibition stamps sold at auction for $89.99 in 2008.
See image below.
Remember this is auction value. Retail would generally be at least $180. This may be less than your father paid; but now, that is what they are selling for.
If you hold onto the the set, it will become more scarce and worth more.
A private seller to a dealer or at auction can expect 30-60% of retail value.
I hope I have helped you.
