Be crazy not to take that offer!
I think the issues some sellers are running into is they paid in LTC and want to recoup the same amount of LTC (or more) when the price of LTC to the $ is now 15x higher. I bought set #13 for 115LTC BUT at the time LTC was trading for $1.80.
The extra 75LTC was premuim (40 was included in the coins) at that time it made sense considering the value of the silver plus the collectors value. BUT sellers are going to have a hard time seeking that same 75LTC premium when LTC goes higher like it is now.
If LTC goes to $1,000 per in 5 years lets say. As a seller do you think someone is still going to pay $75,000 premium for the same 3 silver coins? no
