Cufflinks with George V Gold? Coins?

I have this pair of cuff-links with what looks like miniature Gold Sovereigns on them. All of the details on the face of the coin are identical to a gold sovereign but they are only 1.1 cm in diameter. I can't find any reference to a British coin that small in any metal. My metal test kit is very old so I can't test them but they look like gold. They belonged to my father-in-law who is long dead and are in a Birk's box. For those not in Canada, Birk's was the premiere Jeweler/goldsmith company in Canada for more than 100 years and they did a lot of custom jewelry. There is a foil label inside the box which reads "1/20-14KT Gold Filled". I'm guessing that this refers to the mounts which seem to me to be long after George V reign.
Are these coins? Comment?

 

From their design and the case those cufflinks aren't terribly old. Would you post a photograph of the case itself please? The covering will help date but... I'd certainly think post World War II. 1960s-ish.

There are some novelty 1/8th sovereigns knocking around, and these are 11mm, however I have only seen them with QE2 heads

 

Here is a picture of the case and one that shows the internal label . I believe you're correct about it being 1960s. That's why I believe these were custom made - client proved the 'coins' and Birks put them on cufflinks - probably in the '60s

 

The case is earlier than the 1960s by a decade or two. No, they're not coins. They're decorative and I very much doubt those cuff links were custom made.

Think there's a little corporate synergy here. From wikipedia.org: "In 1953, Henry Birks and Sons bought out Roden Bros. Ltd., a company that produced silver hollowware, flatware, cut crystal, and medals."

The brand was opening stores in shopping malls as early as 1954. Not inconceivable that they developed a less expensive line to appeal to the mass customer.

Thanks for the suggestion. According to Wikipedia The Maundy Penny has a diameter of 11.15 mm which is about right so that's probably what it is but gold plated. Would it be legal to do a bespoke strike?

 

Why would a jeweler create a product featuring a former monarch? Wouldn't there would be a much larger market for the current monarch?
Can these be dated by the toggle style - When did that style originate?

 

According to the internet... Bullet toggles were introduced in the 1930s and popular through the 1960s.
