More info and fair value. Teston PCGS pop 1/0 the Shilling may be easier

See the attached pictures and let me know the information on these please ? Thank You. 
Also have French Colonies for later.

Another approach:

1. Go to the website CoinArchives and click on World Coins.

2. In the search box type in France 1576 teston 1126 (or, for the seond one Great Britain 1787 shilling 3746)

3. COmpare the coin you are asking about to the auction result, and you will have done your own research to answer the question!

Thanks. Seen the sight but thought needed to subscribe
