Overstruck and countermarked coins

Here's an interesting duo I picked up recently,

overstruck with

the overstrike coin is definitely dated 1709. The original coin cut off the date, but if I had to make an educated guess off of the bottom edge of the numbers, I'd guess 1654

Curious what overstruck/counterstruck/etc coins y'all have?

I have this Irish 1 Penny which the reverse was overstruck with Britannia,
but underneath is a wheel ...

and my guess is it was originally the obverse of an unused one of these ...

which is also an Irish 1 Penny, and the original is 1813 then overstruck in 1814. Maybe.

For a collector of overstrikes, it could be very interesting.
Nice find and nice coin!
Here some better contrast:

Oops, I put this in the wrong section last night (I blame the whiskey). Can someone with power move it over to free discussion please?

Edit: Thanks!

Zak, is that penny intentional or a mint error? Pretty cool being from two different countries

Here's another one I got recently. I got a small lot of them uncleaned, this was by far the nicest.

I think countermarked coins are very interesting, but I only own one. It is also my only coin from Brazil, the 40 Réis. This is a very common coin.

I found this interesting one on sale on the internet, but did not buy it:
Finnish 10 Penniä 1865 countermarked "RIIHI"

Riihi means a Finnish/Scandinavian/Russian building where wheat was dried and threshed.
Still there are lots of these buildings in the rural areas of Finland.

Thanks - and they are both from Ireland; the original is from 1813 and maybe too
many were made and some were re-struck intentionally later on to make the 1814 (1816) penny. I just now made this rough animation in which the wheel just about matches ...

So I guess not enough pressure was used in the re-strike to obliterate all of what was originally underneath. The obverse looks alright so it was just the design coming through on the reverse.


P.S. I tried that with your first images but not as easy as they were re-struck at different
angles so the design does not appear in about the same place ...

I don't collect countermarks, so to me personally, they might as well be PMD. Thus I often avoid them, and don't have many in my collection (although I might make a future exception for an otherwise scarce coin).

But here's one from my early days of collecting; a 1807 George III halfpenny with a "£" countermark (I think) upside down on the obverse:

I got the overstruck spanish ardite of Carlo III too but mine is as ugly as possible .

I got few more from the mamluk sultanate but I didn't manage to identify them yet.

@Cass
I thought the countermark on your coin was a gun or something like that at first

​Well, I'm not 100% sure it's a pound sign either, so who knows? Maybe someone really didn't like George III back in the day.

I just remembered I also have a Spanish/Mexican 8 reales coin of Carlos IV that bears quite a few chopmarks; mostly from East Asian merchants, to ensure validity.

​Whoops, forgot to attach it:

There's a couple of flower chopmarks on the neck of the bust, plus a few distinct Chinese characters (考 is visible in the field in front of his face).
