1 Koruna Czechoslovakia - Trial Strike

[Mercuryman]

I was hunting through the foreign at my LCS and pulled out a coin that appeared to be silver.
I decided to look it up and its a 1922 1 Koruna. Numista says its copper-nickel and should weigh 6.66 grams.
But it also gives the disclaimer :
"Krause lists two trial strikes (Pr1 - Aluminium and Pr2 - Copper-nickel) without any additional information.

Without any connection to Krause listings, here is list of known trial strikes:

1922 - Gold, 14,68g, reeded edge
1922 - Gold, 10,46g, smooth edge
1922 - Gold, 11,35g, reeded edge, without year and value
1922 - Silver, 7,23g, without year and value
1922 - Silver, 9,84g, without value, reeded edge
1922 - Silver, 6,01g, smooth edge
1922 - Silver, 8,65g, reeded edge, without year and value
1922 - Silver, 6,99g, reeded edge
1922 - Aluminium, reeded edge
1922 - Aluminium, without value, reeded edge"

My coin weighs 6.88 grams and has a little wear. So it appears to fall under the 6.99g silver reeded edge coin. I cannot find any information on this coin... i found one website selling 8 or so of all the different trial versions for around 12,000 Euros.

Does anyone have any thoughts on how to figure out the value of this? I'm stumped.

No idea at all except check to see if it's silver. What a cool hunt to be on.

Yep! When I have some free time I'm going to take it down to another LCS so they can use their Sigma tester on it to verify. I'm not sure what % silver it would fall under though, will have to play with the tester to figure it out. There is literally no information about this coin online... its bizarre. Even stranger is that the Krause listing doesn't even mention it. Would be curious to know how many of these are actually slabbed from NGC/PCGS.

I wonder if somebody could help you...

There is no mint mark above the date and it was certainly not a proof.

There would have to be a real coin expert there to figure this one out! I'm thinking of sending it to get graded... I'm not really sure of any other way to have it verified. Maybe I would have the only one slabbed? Not sure there is really a market for this anyway.

Added photos. Not the best quality. I would post it on my scale. To show 6.88g but i don't have it with me.
The scale is accurate as well

Thanks for adding the picture. Very cool. A little piece of history. I hope it's worth a bunch.

I went back to the same lcs I found this at. Went through about 30lbs of his foreign and i found another 1 koruna 1923. This one weighs 6.55g and has been circulated so it appears to be the standard coin. The 6.88g coin is slightly thicker but their diameters are the same... The mystery continues.
