Got a link for more info on this coin, perhaps the original selling thread? I’m surprisingly unfamiliar with this one. Kudos for holding onto it so long (assuming). You could probably trade it for a nice house now! Not bad.
Originally out of The Isle of Man (UK) they were made in various metals, platings and denominations.
I became the UK/Global reseller for them in 2016.
An old sales thread (not this particular coin) is here ...
https://bitcointalk.org/index.php?topic=2110975.msg21105206#msg21105206Very few (of these 10's) were sold loaded. Under 5 iirc.
TGBEX made 0.5, 1, 2, 5, 10, 20 & 50 with a 25 Error coin that never made public circulation
Due to a design error, the Hallmark for these Silver coins was hidden by the Holo as it was so large.
This is whats there
