I see you're account is set that you can't receive PMs from members. I researched these online to determine composition .. Here's what I have:
50% silver coins ... 1 1935 Irish Shilling probably VF or better, 1927 1 escudo, Portugal ... maybe VG at best, 1 1953 British Shilling VF or a bit better perhaps. 1 1941 British sixpence XF most likely. 1 1941 threepence to match, in similar grade. My favorite is the Portuguesa 2$50 with a nice ship on the obverse. It's dated 1951 and has considerqable mint luster yet. Total weight 26.6 grams
75% (.750) silver ... Philipinas 5 pcs 1944 10 centavos in XF-AU ... and a 20 centavos 1917-S that has something going on with the last digit in the date. I'm attaching a picture of that one. Total weight of the .750 .. 13.9 grams
.800 silver ... Canada 2 1957 quarters 1 XF and 1 AU, 1 1940 dime in VG, and 1 1945 dime in XF 16.3 grams total for the .800
.925 silver Canada ... 1 dateless quarter Georgivs V in AG, just worn. Same Devices as the lone 1920 dime that's also pretty worn, but has a legible date at least. 1 1901 5 cents "love token" 4 small holes, probably the centerpiece of a bracelet. There's 1 small link attached which is likely gold. 8.4 grams.
The medievel pieces are proving to be a little more difficult to research right now... but I knew where they were from a few years ago. They're about dime sized, crudely hammered, with a letter H in the center of the obverse. They're worth about 3 bucks each.
That's all I've got in the "non-US" silver department.
