I wish i could agree Jeffro, that there is no basic meaning that will subliminally instruct readers unfamiliar with
the currency depicted to donate a particular amount. And it is true and obvious that notes are preferred to coins as they were in Jesus' day .
However, the lowest denomination note with a yellow tinge in Ewe speaking countries is 500 francs. Given the average wage over there pays approximately 182 francs per hour, that represents app.2.8 hours work. compare that to average wages in western countries and you'll find that equals around $75,, still representative of a large amount.
