Depending on the date of the Libertad, there are some dates like 1997 and 1998 where they only produced 8k-9k per fractional. In the last 5 years or so, these have become more collectible and less bullion driven in the marketplace. Even the later dated examples, the mintages are still pretty low in comparison to their one ounce cousins.
Some even lower mintages like in the 3000 to 4000's range I had a link to the bank of Mexico that gave mintages most of the fractions were below 10,000.
I would phrase it that it costs the same. If it costs $5 to make a coin, as a percntate of a 1/10th ounce silver thats huge, as a percent of one ounce silver not too bad.
Agreed. I can't see why it would cost more to make a smaller one. Its more the demand where collectors can afford a smaller fraction that drives the price up and creates their higher market value.
like rocky said, basically all fractional .999 silver has large premiums, if you shop around and are patient though you can usually find some around melt. fractional silver is actually my favorite to collect because they usually arent easy to find. This is what i have left of my fractional collection including a 1/20 libertad and the only one that had a heavy premium is the one tenth pamp suisse. i am really curious to what it would bring on the bay.
