Unknown coin

Could you identify this coin please?

Smekin you should create your own topic, not use someone els´es.
Smekin your´s seems to be a modern replica of a Antique greek or roman coin. Most likely a tourist piece from a shop or museum.

tweed Im not sure what your coin is but it seems to bear the portuguese cross and arms. Can you provide us with the approximate weight and diameter?

Hi, It's diameter is 28mm and weight is 30gm approx.

Thanks

its looks like an "Crusader" holland bronze coin & I also think it's a Genuine.

It seems a Jerusalem cross with dots ...

It is surely a portuguese or portuguese colonial coin from mid 16th century to start of 17th century

we are getting closer

Porto, Portugal, 200 reis, Joao IV (1640-56), rare provenance. Gomes-29; KM-50. 5.99 grams. Nice full shield and cross despite corrosion all over, somewhat silvery from cleaning. The "Standing Cannon wreck" was brought to light in the Christie's (Amsterdam) auction of March 1983, described as "a large outwardbound Portuguese Eastindiaman... [whose] name derives from a large 10 foot cannon protruding through the sand bottom towards the sea surface... sunk... circa 1690 after colliding with a sperm whale, the remains of which were discovered under the hull and ballast pile." Pedigreed to the Charles Eidel collection, with certificate and Certi-Grade Certification Institute photo-card #01254. Recovered from: "Standing Cannon wreck," sunk ca. 1690 off Bay of All Saints, Brazil ($200-300)
