4 Unknown Coins I need help with

I bought a bunch of coins for quite cheap and these are the only ones of the lot I can't identify. The largest is so worn you can barely see anything much on it, and one looks like a really really beat up roman coin, but I'm not sure.

Less than 1g, 9mm.

Says Nuremberg on it, thinking it might be a jetton or something. less than 1g, 11mm - SOLVED!

2g, 15mm - SOLVED!

all I can really make out are the scales. 30mm, 17g. - SOLVED!

Thanks for any help

Miniature jeton/token indeed.

​Great, thanks for the info. Much appreciated.

Here's the closest I found for number 4.

The weight and diameter of yours are a little smaller, but that may be due to how worn it is.

Coin number 3 looks like the seated river god, but I don't have any more suggestions than that.

Even before seeing the replies I was going to say
2 = miniature play money coin
4 = a French coin
so I agree with those replies.

I see how rough the edge of 3 is; that is because someone has cut or stamped
the edge from a 1/4 Penny (Farthing) United Kingdom coin >

The other two similar design coins are larger, so cannot be from one of them,
namely 1/2 Penny was 25.5mm and 1 Penny was 30.8mm

​Thanks, looks like that's it. My measurements might be a little off as I was using a larger kitchen scale and a tape measure. But it is pretty rough anyhow. Thanks!

​I think you're right about number 3. I thought it seemed familiar. It makes sense as well considering I found a 2012 £2 which had been intentionally shrunk in size.

​Very close!, but judging by the diameter I would say the sous:

1793 W (Lille) by the looks of it.
