Seville or Bolivian silver 4 reals coin

Bolivian or Seville silver coin (S on the left hand side may indicate Seville), 4 real coin, 3mm thick, 33mm approx diameter, hammered coin, hole present for personal wear, discovered within personal items of a dive captain in the 1980-90s with dive logs to ship wrecks in the Maldives, no direct evidence but may have been a personal find, would really appreciate good reliable identification and valuation

Hello,

If real (I have some doubts) , the coin is from Sevilla.

Regards

Thank you clarifying Sevilla, can I ask what your doubts are, image wise, through looking online at similar items, they are all imperfect in condition understandably, it is very shine and clean possibly from acting as personal jewellery wear, the weight is approx 12grams if that helps, 

kind regards

Hi

This type of coin was struck under the reign of Felipe ll (1556-1599) in 8 different mints in Spain.

Sevilla (S) coined them without date till 1588. From 1589 on, date appears verticaly right of the coat of arms, displacing the value (IIII°) to the left side. The value (vertical IIII) returns to the right side in 1597-99.

Your coin has no date, so it belongs to the first type. Here are picture of the two subtypes (N°170 and 171) of this period (catalog Áureo & Calicó, Barcelona).

Apart from the underweight (which might be explainable due to wear), what makes me doubt is:

A) the general color and the design,  which is not clear, in some parts quite chaotic and not sharp;

B) the upper part of the coat of arms is odd (or off);

C) the strange hook-like figure in the lower left part of the coat of arms;

D) the S from Sevilla which is off; 

E) on the reverse side upper rim, where REX  ends, should be a little cross, your coin shows something different.

But inspite of all that, lets wait for another opinion; it is difficult to expertise not having the object in hand.
