Can't sell on the CCF until you have 250 quality posts.
eBay OK.
Need pics of your coins for us to assess condition vs value.
In the meantime, search eBay for equivalent coins to yours, with which you can compare. Bear in mind that other sellers prices on eBay can be a very unreliable guide.
In my view,
NGC World Coin Values
are top of the market dealer seller prices, but with a bit of nous, and accurate grading of your own coins for yourself, you may be able to arrive at fair value selling prices in the current eBay market place.
Price research need to be done.
