British penny values 1850s to 1969s?

I have multiple lots of British pennies like this. I want to pick out a few and swap/sell the rest. 
 The problem is I have no idea what’s a fair price for each. Is there a website that shows the average values for each showing values across all conditions? 
like this one from NGC coin?

Maybe here?  https://www.coinsanduk.com/

Being at Numista there is large chance that you may find out its own estimations too. It is just enough to use correct settings and open a necessary article, which described the coin in question.

Tony Clayton's website is a respected British coin value resource https://coins-of-the-uk.co.uk/values/penny.html

Funny last link!
It is in complete contradiction with Numista policy. The person, who cited it, represents Numista team and personally rejects information for the Numista catalog,  widely known: it is just enough to check the types by looking at the pocket, it is even published in the link, which he proposed to use, but he applies all personal efforts  and power not to allow the Numista collectors to know it!
 

Thanks RadRick! I’ll try that one.
