France: 5 centimes 1856D (sizes / tailles)?

Hi,

has anybody an idea how to tell the difference between a small and a large “D”? I have given up after having hunted images on eBay and using my own two coins😵‍💫

Thanks for your help.

N#485

I looked in Gadoury (the 24th edition, nominally the cited version for Numista) and there is no mention of D sizes for Gad# 152.

Does anyone have earlier versions to see if this is a change? Anyone have Le Franc? 

I have it but it's not mentioned. On thr French site it's said to en error in numista. 8 lines will be changed into 4.
