Is anyone able to identify these very low grade coins/tokens?

1.
Possibly British or Irish. 7.91g; 2.9cm diameter

2.
5.32g; 2.2cm diameter.


3.
I can barely see some lettering on this counter-stamped coin (...rite reg...d...). 4.13g; 2.2cm diameter.


4.
This might be Victorian copper. 6.30g; 2.4cm diameter.


5.
1.54g; 2.1cm diameter.

Thank you so much!

Wow, I love a good mystery!

1. Judging by the bust and diameter it's probably a 1806-07 type George III halfpenny:

2. Probably a Nuremberg jeton or some other counting token:

3. Judging by the legend (BRITT: REG is what I can see on the right), probably a Victorian bun head bronze denomination; but 22mm is right in the middle between farthing (20mm) and halfpenny (~25mm). Perhaps a colonial?

4. No idea, sorry.

5. Probably a farthing; I think I see the digits "75" on the reverse, so possibly 1775.

Thanks a lot CassTaylor!

Tis' nothin'.

If anyone else would like a stab at identifying the ones I missed, please go ahead.
