Just a comment, I love the coins but I think they would have been better had the various denominations mathematically worked together. Meaning, 5 LTC is 1/4 oz silver, and 10 LTC is 1/2 oz silver, so 1 oz of silver should have a value of 20 LTC for it all to work together.
My mindset was to give people the ability to store more LTC on the biggest size coin.
In the U.S. legal tender we do not have a 20cent coin. We have nickels (5 cents), dimes (10 cents), and quarters (25 cent). So perhaps I also did it unconsciously given that is the currency denominations I am used to dealing with.
But you have a good point the math between them is a bit off.
Well, truth be told, the silver quarters of the day held 2.5x the silver of a silver dime. The weight and purity of pre-'65 silver coins in the US all worked out mathematically. And, you may not have known this, but indeed there was a 20 cent silver coin minted in the US, with the amount of silver identical to two silver dimes.
That coin didn't take off very well, but throughout the history of US silver coinage, the amount of silver aligned mathematically with the denominations. But, I understand that these are your coins that you designed as you saw fit, and I do see somewhat of an added benefit to having the largest coin (1 oz & 25 LTC) being designed to be more desirable via more LTC stored on the coin.
And by the way, thank you for the 1000 LTC donation to the litecoin development team. Your donation is probably the most significant gift they've recieved thus far. I am a firm beliver in LTC, and your coins bolster the trust I have in the future of these coins.
