Looks nice, but if so, that 1/2 oz silver 10 LiteCoin round is still only worth 1/2 oz silver, about $10 -
If its current rate of 10 LTC =

at least. Not sure where you get $10.
Current price of silver is $21.81 oz, So that half oz coin is worth $10.90, it dosent matter what it says on it, you can put anything you want on a silver coin, its easy to do and it dosent make it worth anymore, silver is silver. It would be stupid to pay $20 or $30 for a $10 piece of silver.
It completely make sense yes anybody can write or design anything on silver it doesn't increase the value . If somebody real fan of Litecoin then buy one and keep it for them-self as we buy fan t short , Mugs similar kind of apart from no use for litecoin value or blockchain . Its clearly some marketing gimick or the guy who has done this having good marketing strategy.
