I really think this is a jeton with symbols for luck on both sides. It's a gamblers coin. I would translate the legend on the 1st side with "now is a good opportunity" and the one on the back to something to the effect of that what I wrote before. Maybe someone with a degree in Latin can help?
You may be right, but I am having trouble with your interpretation of "colam" as "I pray". It clearly appears to be a 1ps future of colere. I do not think that you can impute that sense to colere. And if "haec" refers to the coin, then what word in Latin? The usual word "nummus" is masculine and would require "hic". That is why I said that the context is missing. What was the author thinking of when he used "haec"? I think you are correct about the front, but it could also mean "this happens at a good time".
