1927 Silver Soverign Pattern

the old 2x2 had (great Britain trial strike unusual piece) is the description that was on
the 2x2 and it was a very old 2x2 I did read they added the SA IN 26 27 28 29 WHAT MINT WAS IT IN SOUTH AFRICA looks very real in hand sap didn't look to good in the old 2x2

Looks like a jeweler's copy, this case made in silver, but was never gold plated.
Sharpness of detail is lacking, which leads me to think 'copy' or 'replica', (but not necessarily 'fake', with the intention to deceive).

London Mint Museum ?

the word "silver" appears in the title of this thread, but I'd query "Why ?"

A sovereign is about 22mm, and a tad under 8 grams.
The nearest silver coin is the shilling - slightly larger at 23.6mm; but weighing 5.66g.
The variation is, of course, attributable to the inherent difference in density between gold and silver.
But the "coin" posted in this thread is less than half the weight of a shilling.

So, I'm thinking that Shane's coin is of some base metal, and probably Sap's suggestion is "on the money".

Shane raises a few other points -
if I recall what I read a few years ago, the South African mint was in Pretoria.
They produced sovereigns each year from 1923 to 1932.
A new effigy of KG5 ? This looks just like the effigy of KG5 used on coins of most countries in the Empire, except of course, Australia - we used a crowned head. The uncrowned head was also common on British medals.

I'm wondering if it's a counterfeit, still waiting to electroplated, before being passed into circulation ?
