Coinage in the Roman Economy, the Syrian tetradrachm was 35-36% silver at the start of Gordian III's reign and dropped to around 25% by the year 240.*
At an average coin weight of 12.5 grams, this means the actual silver weight would have started around 4.4 grams and then dropped to just over 3 grams.
