Alma 11:6 - 11:10
Alma 11:6 A senum of silver, an amnor of silver, an ezrom of silver, and an onti of silver.
This is the silver coinage: Senum, Amnor, Ezrom, and Onti.
Alma 11:7 A senum of silver was equal to a senine of gold, and either for a measure of barley, and also for a measure of every kind of grain.
Here is how the value of the gold and silver coinage compared along with gains of various kinds. Senum (silver) = Senine (gold) = measure of barley = other kinds of grain.
Alma 11:8 Now the amount of a seon of gold was twice the value of a senine.
Two Senine of silver = One Seon of gold.
Alma 11:9 And a shum of gold was twice the value of a seon.
Two Seon of silver = One Shum of gold.
Alma 11:10 And a limnah of gold was the value of them all.
A Limnah of gold equal in value to the one of each added together.
Not sure if that meant all the gold and silver coinages added together or just the gold coins added together.
