Try to unbent or not

I receive this and dont know if is better to keep it like this or try to unfold?
Without id until now.

Have a nice day and stress-free health.

In my humble opinion, it will definitely crack, the process has already begun and an irreversible state. There is a small chance, however, that even if it settles, it can hold together in small parts, but part will definitely be separated.
Here it is either or.
It's not just that every solution is bad and it's just a matter of preserving the fathers' heritage. I personally would put it between two thick felt fabrics or other semi-hard gums -and I would gently push either my palm or my finger or my hammer.
,, But in advance, pray that you light a candle and spit for good luck.,,
this bursts you squeeze the cracked seam and when you push the slack on the other side. ( so just push from the other side and just hope)

Keeping it in this state doesn't just make sense as an ornament -It is a destiny.

Bending such coins back without doing more harm than good is a laborious process which needs quite a bit of experience.
If you don't know what you do the only thing will be a broken coin. So ... no.

A very recent post about straightening a coin. Watch the video then decide if it's something you're comfortable doing. I'd suggest you have 3 or 4 you're willing to snap in two first since it will take a lot of practice to do right.

Warm it up in an oven to soften the metal first. Then very gently squeeze with a clamp between two pieces of soft wood.

Keep your fingers and toes crossed at the same time ...

There is a coin dealer in England who specialises in unbending hammered coins.

Is this the coin you have?
