When Don said "Use 27 grams for an 8R to determine its denomination." he was talking about determining if it is a half reale, one reale, etc.
27 grams is used for an 8 reale coin.
4 reale would about 1/2 of 27 grams (+-13.5 grams)
2 reale would be about 1/4 of 27 grams (+-6.7 grams)
1 reale would be about 1/8 of 27 grams (+-3.4 grams)
1/2 reale ................................. 1/16 of 27 grams (+-1.6 grams)
