CAN ANYONE IDENTIFY THIS?

Any information on this would be very helpful.

Plastic is sealed so I can't tell the weight of each… HELP!

Based on the looks, you got silver proof variants.

I've done that and those are different coins from my set. A seller from eBay is selling a set with a box but no information that I can use.

Another seller posted this:

Says Sterling Silver.

But I doubt it if you bought it for US $19.95.

Right? Haha. But there is no other examples I can find. Any other information? Please…

Maybe…

Without assay marks people can think it's just silvered, if you don't take it out and test it so you could get it for a cheap price. On the website linked it states ‘out of pure silver’ if it has the ‘pure silver’ stamp it could be from 999-950 from that era (I can't decipher the number in the diamond stamp).

Sorry, I did not see the link you posted at first. I looked and I saw three of the coins on that article. All three say made of 19 grams of silver. Did I just get lucky?

Does this mean I have to open the case and find the stamp? I'm guessing the stamp would be on the side? I don't see any on both sides

I don't think so. I just noticed that yours is different from the ones in the picture I posted.

Those stamps are not on yours.  I think there is a silver version and a non-silver version.

Yes. Mine only has one mark like the one on top. Safe to say I have the non-silver version? They are all missing the assayer and privy marks.

I was able to open the case without damaging it and here's their individual weights and measurements:

US Pavilion = 14.1 g - 25.2 mm

Osaka = 13.9 g - 25.2 mm

French = 14.4 g - 25.2 mm

British = 14.0 g - 25.2 mm

Canada = 14.2 - 25.2 mm

If you could measure the thickness you could estimate the density.
