Fungibility of 40% silver coins?

[enmaku]

So I'm just curious, I've dealt in 999 silver rounds/bars before and I've dealt in the old 90% silver US coins and I've never had many difficulties finding someone to buy or sell at or near spot/melt prices. I've recently obtained some of the pre-1971 half and dollar coins which are about 40% silver. I've never bought or sold these before and I'm not a coin collector, just interested in precious metals. So my question is this: In your experience, how hard/easy is it to find a buyer should I want to liquidate some of my 40% silver coins, relative to finding a buyer for 90% or 999 silver?

I don't know what you mean. Can you please be a little more specific? Thank you.

It's hard to sell: 40% silver coin can be easily counterfeit and it's hard to proof because the silver content is really low. If they have some historical value you can try to trade with collectors, otherwise is near impossible to sell (or almost so is here in Italy).

According to this http://www.coinflation.com/coins/1965-1970-Silver-Kennedy-Half-Dollar-Value.html , the half dollars are worth .854635461 BTC at its current market price.

Just thought of something after I wrote the above. Maybe someone could take the incentive to create a simple web page showing the current melt values of US coins expressed in BTC. Hmmm!

Actually that's the value of the raw metal in the money, but if see the auctions below you can found that 3 coins worths about 1.73703703704 BTC (0,579BTC/cad) few minutes before the end of the auction, while some other another auction arrives at 0,82-0,86BTC but I think that is more for collectors effect than for investments.
Here  in Italy  is possible to find silver eagle dollars sold in coin shop at prices 40-50% over the spot, and some old silver coins like 500lire is sold at non less of 2BTC for collectors with top of 4-6BTC, while actually that coin worths less than 1,6BTC in metal (11grams of silver 825/1000). But other coins with the same amount of silver but larger mintage are sold at 1,3-1,4BTC.
