No chance with that over here... Actually up to right now I did not even know that once I myself had silver coins in hand. They only german one was cancelled in 1974.
Either you can buy small lots of 90% Silver, American Coins, (there are some 40% ones two) or a larger bag of mixed American coins as an investment toward a future calamity stash, from the online bullion dealers whom also sell "junk" silver in rolls and bags.
I just checked one such dealer and they, for example have a $5 roll of 90% silver (50 American Dimes) listed for $105 U.S.
Canadian dimes and other silver for circulation Junk coins are only 80% silver, and so on and so forth.
Of course in the EU , you'll have VAT, (etc?) but at least you have something stashed away for a really bad month or so for bread, eggs, etc.
Think about it and avoid Bullion coins other than junk, as they can sell for much higher prices, in any metals, just because they are Mint or in a better graded condition.
IE. A few years back, I wanted a small gold round or bar, one gram, to test my metal detector in various grounds to get my setting right. I went to my favorite gun store which has a decent coin shop also, and looked at their least expensive round, no a government issue.
Gold was about $38 a gram that day but the shop had this round at 50% higher price than the gold value.
I was able to get that down to 25%, and bought it and have kept it in 'Mint' condition by keeping it in it's small non-metalic case, which can be buried and recovered easily.
One gram of gold is a very small, thin affair and I keep it in my wallet, for detecting but mostly because it might come in handy in an emergency, where a card will no do the trick, or for a stubborn trader of some happy encounter with the unexpected.
It's the only gold round I have, no bars either, but it's enough metal for me.
By-the-way, on a Garret Ace 250 metal detector, gold often sounds and reads like an American Nickel, so did all your targets, I found my first gold ring like this, and the look of my Rozeann's face, when I opened up the earth to take it, was sheer amazement. I can still hear the astonishment in her voice when she gasped, "It's a gold ring.... "
That was and still is Treasure in my mind, though the ring is long gone.
Anyway, if you want small silver to trade with, there are easy options, so long as you have the cash to buy them or the ability to go out and find them for yourself.
Cheers.
