Yes, I'd say that the first, second, and second-to-last entries here
do seem to support L-C's definition.
"Gold money is a tangible value in itself and a token of wealth actually produced... When you store your savings in the form of gold coins, they represent the goods which you have actually produced..."
Thus, wealth is: goods which have been produced.
"Money cannot function as money, i.e., as a medium of exchange, unless it is backed by actual, unconsumed goods."
Again, unspent production.
"Money is a tool of exchange; it represents wealth only so long as it can be traded for material goods and services. Wealth does not grow in nature; it has to be produced by men."
And once again, the end product of production, i.e. that which is produced by man, and a thing which is equivalent is that which can be traded for goods and services.
