what about creating a specific field to record the information with a link to the original coin?

Countermark is preferred.  https://en.numista.com/help/coin-name-142.html

Countermarks

Specify in parentheses the mention “countermarked” and the value of the base type if it is different and known, or the name of the issuer or the ruler if they are different from those who used the mark:

• 12 Maravedis - Philip IV (Countermarked 8 Maravedis)
• 40 Batzens (Countermarked French ecu of Louis XVI)

it's not so clear to me

I saw that too. But the examples that are used for counterstamp no longer say counterstamp.  The guideline text just hasn't been updated.

I found this issue some months ago. According Numista they are similar. A countermark is made by hand and a counterstamp is made by machine.

I like this, and the new field could be used in other derivatives objects, not only countermarked and counterstamped, but also replicas, imitations and contemporary counterfeits. There is a similar suggestion: https://en.numista.com/forum/topic129036.html
