melt temps (oC) (oF) Copper 1084 1983 Silver, Coin 879 1615 Silver, Pure 961 1761 It's clear that 40% is an investment . The 40% is an Alloy & thats what I find troubling particular the melt temps are close . If you research the net you can find info on melting AL CU AG AU 90% silver coins & there are plenty of back yard foundries manipulating these mentioned metals But doing a search on melting 40% & it is a dead end ( for me ) What you get is info of the 40% investment info There is an acceptance of the silver content & mathematical conclusions to sell them .Thats half the Battle as value is always based on what a person is willing to buy .If people except the AG weight as fact it's a trading silver coin . Yes there is money to be made as it has a silver pedigree . But part of me feels cautious till a question can be answered - How hard is it to undo the silver copper Alloy ? It's well and good to know when the mints made the 40% yes indeed silver was used & as an alloy the coin proves qualities exceeding CU coins but the tainting of CU is evident compared to a .999 or 90% . If undoing the Alloy was easy it would be all over the net , Consider that gold from computer boards is no easy task yet a few key words and your there . Silver is valuable and no one is expressing the ways to undo the Alloy bond of the AG CU 40% that are readily available and can even be found at face with some luck . Considering pure silver coins are more available then ever in history and the melting of 90% does go on & can be seen on youtube Particular to 40% with there fewer years of minting there is a reason the 40% are here - IMO they are not melted as the first choice - If at all ??? During silver booms there low cost and or luck finds should of made them disappear like I said we have a 5 year run of there minting & there are plenty to be horded after 45 to 50 years . I realize it's a stretch but they kinda are the silver Fiat coin . You put trust in there original composition the explanation of ounces of silver in 10 pounds of the 40% 1/2 , but really I think that silver is locked in that coin and not there . it's unobtainable .Wile it's a coin of trade I feel uncomfortable in blindly with confidence loading up . As it is a voice in the back of your mind says what is silver bottoms bad . Then you say well its industrial & .999 has to be desired as there is a need and pure is pure . It could be at that moment the truth will show of the 40% 1/2 melt value not worth the effort . Since CU and AG as metals are excellent conductors for modern electronics , the Alloy AG CU is usable so some value must be there but .999 it's not. Till I can find out the truth of undoing the Alloy bond I will proceed with caution . I will get a few here and there but I stack particular cause .999 is real and pure I can count on that . When it comes to the 40% 1/2 during a crisis price up or down show me the money - show me the money .

It is key to note as the 40% coin from the mint it is not the alloy known as AgCu http://pubchem.ncbi.nlm.nih.gov/compound/16217327#section=Top so wile I will not stack in a different direction ( I will hold tight on .999 ) But I do feel having some 40% is safe as the coin is constructed as separate metals . This also holds true for the IKE 40% when you do the math seven 40% coins are a touch over a silver eagle in grams (takes 7) so the price is low per $1 face but clearly one can find a round at a better completive price
