1607-GM (my coin) and 1607-MG (exclusivecoins's coin) both exist for Felipe III 2 reales [résolu]

I purchased 1607-GM from La Dobla in late 2019 or early 2020.
At that same time I queried 'juste-exclusivecoins' (eBay ID) about his 1607-MG (M on top) because i was told by La Dobla that i had the only 1607 for Granada. He explained both letter varieties exist and that it's more like probably 3-5 of each variety actually exist rather than unique.

Another post where i need to fix it and provide the Numista coin link:

Thanks once more.

Referee was informed.

Your variety 1607 GM has been added. Congratulations for your coin: full date, mint and assayer marks, rare, VF

 

I have no proof of the existence of the 1607 MG variety.
