Stacks of buttons which didnt help matters but one very impressive livery button which was probably best find of the day ! The final tally from a wet and windy Norfolk

Couple of pics . The smaller one was same field but found the other day .DaveP wrote: ↑Fri Mar 12, 2021 8:27 pm Well you did better than me. Imagine, a glint of silver covered in mud. The tantalising hint of a figure. A 1981 2 Franc piece - what a let downDamn those Frenchies!

The darker flint looks like a machine strike as the ripples are too intense and more typical of more than a hard hammer blow. However, a closer look at the right hand side, from both sides, would help. What's the other side of the lighter one like?
Sorry Paul but I'm not seeing anything in the new pictures to suggest these are worked. It's always worth keeping in mind there's a lot of waste material (debitage) just to prepare a flint core or tool. Think of it like peeling a carrot - you end up with a pile of shavings with straight edges that, laid out flat, would look like they are worked but just end up on the compost.

Did the dark flint in the first picture have any features on the other side?
