Help Please

I have had this in my collection for over 30 years and I do not know what it is and if it has any valuation to it.

It weighs around 2.4 ounces sorry and is 9 mm thick and the Diameter is 3.4 cm
The stamp on the side looks like a HP? this has 4 stamps on the side.

the date says 1525 with an S & I above the date.

I cannot tell where it came from as I have had it over 30 years so a long time to remember.

80grs or 2 lbs? How can 80 grs also around 450 grs?

Something trying to emulate or similar to this with some differences? With the information you provided I have no real Idea but maybe this will help to put you in the general direction.

Better, sharper images please?

It's a medal evocating a coin from BOHEMIA : minority of Louis (Ludovic) I, guldengroschen 'Joachimsthaler'
LUDOVICUS-PRIM-D-GRACIA-REX-BOE
ARMA = DUOB = SLICOUV = STEFANI = ET = BRATR = COMITU = D = BASAIA
Arma Dominorum Slickorum Stephani et Fratrum Comitum de Bassano

This medal/token might have been hammered for tourists in the mint museum of Jáchymov

Thank you everyone for taking time to reply, can I ask If there is a value to it, and how would I go around finding out what it could be worth?
