When and where was the last silver standard circulation coin issued?

I think it was in the middle of 70s in West Germany and Austria.

I think the 10 and 20 Nuevo peso bimetallic coins from Mexico, which had a sterling silver inner ring, stopped being produced for circulation in 1995.

Those two types appear to be the correct answer, yes. IIRC there was a bunch of later NCLT issues from various countries that were supposed to end up in circulation (but mostly didn't), but I don't think any of them qualify as "standard circulation".

​I never knew that some NCLT issues were supposed to circulate. Could you give some examples? I would love to read up on them.

​Well, the ones I was thinking of were the Canadian "$20 for $20" series, such as this type. There were many other series available for face value; to the best of my knowledge, all of them are commemorative. Some of the earlier ones would probably have circulated somewhat. This 2001 Spanish type is listed as a "circulating commemorative".
(I've heard somewhere that some - French, German, Austrian? I forgot the details - silver 5 and/or 10 euro coins, also issued for face value, saw some circulation, but I'm not very confident which types this would have been referring to. If this one, it could in principle have been considered a standard circulation coin, as it is not visibly commemorative.)

Actually, now that I think of it, depending on the specifics of the question, my original answer of "1995, duh" might have been incorrect. Italy used to produce a 500 lire silver coin for standard circulation; later, the 500 lire denomination was switched to base metal, but the original type was still made (in sets) right up until the 2001 euro changeover.
Technically, this means a standard circulation silver type as late as 2001; this and the French 100 francs (in a similar situation, except with less original circulation) are, to the best of my knowledge, the only post-2000 coins listed as "standard circulation" on Numista.

EDIT: see also the description on this 1996 Spanish type, which is a very good description of most of those "circulating" late silver types.

EDIT 2: for some reason the forum software decided to blank my post when I edited it. Fortunately I happened to have a copy backed up.

EDIT 3: was unable to post the edited version, so putting the edits in a separate post.

​I was thinking that the Italian 500 Lire coins and the French 100 franc coins didn’t count because they weren’t meant for circulation in their final years. I definitely see what you mean with the silver commemoratives though - but I think people squirreled them away because they weren’t what people were used to, and non collectors might have thought they were valuable.

If I remember correctly, I think the Canadian $20 for $20 series was a way for the mint to make extra money since the silver used to make the coins was worth much less than the $20 they received went people bought the coins, and the fact that people probably wouldn’t spend them meant they would basically get to keep the $20. However, I think I read a story where someone tried to cash in their collection of $20 for $20 coins when they were lacking money, but the bank refused to accept them. I believe that this caused a debate of if they were legal tender and banks had to accept them, and I think the government said that banks did not have to take them (I think, correct me if I’m wrong).

​I agree with you about the 500 lire and 100 francs.

I also recall having read the same story about the $20 for $20 (and a similar story from, IIRC, England), but, again, also vaguely recall a story from elsewhere (France?) where similar coins did circulate at least a little.

The 20 for 20 in canada was stopped because the coins were legal, but not legal... kinda!
Basically you couldn’t and still can’t spend them in a shop. If the store owner did take it, he’d have quickly regretted it as he would have to fill in a special form when depositing it at a bank and then wait for 3months for it to be accepted.

Once people realized that the silver was not worth $20, many tried to spend or deposit these coins and quickly realised the headache involved in getting their money back. The mint as a result had to stop the programme because they were inundated with complaints and requests for refunds.
