is there silver in Dominican Republic coins from the 70s-80s?

[smb]

I have 3 coins from the Dominican Republic:

1975 - 10 centavos (marked as 2 1/2 gramos)
1979 - 25 centavos (marked as 6 1/4 gramos)
1981 - medio peso (marked as 12 1/2 gramos)

Is there silver in these coins? Is that the silver content (marked in grams) on the coins?

I've been trying to find reference online but to no avail.

I was checking out silver values all day. Hope this helps.

P.S.: I forgot, welcome to T'Net!
