What is the value of 1975 5 PTAS coin?

Answer 1

Presuming that you are referring to a 1957 5 peseta coin from Spain, the answer depends on the condition and on the year of mintage. The 1957 date refers to the date of authorization - the mintage date is actually located on the back, incused in the star located to the left of the eagle (it is very small; you will almost certainly need a magnifying glass). The date is two digits (the initial "19" is implied), and will be between "58" and "75". It is also possible that there will be a "BA" in place of the star. The BA date is worth (according to the Standard Catalog of World Coins), about US$100 in Very Fine condition, US$150 in Extremely Fine condition, US$225 in Uncirculated condition and US$300 in Brilliant Uncirculated. With a couple of exception, the other dates are worth less than a dollar unless they are in Uncirculated condition or better (the exceptions are the 63 - worth about US$15 in Extremely Fine conditon - and the 58, 61, and 66, which are worth about US$3 each in the same condition). In Uncirculated, values are about: 1963-US$125, 1958-US$50, others 1959 to 1966-US$10 to 25, 1967 to 1972-US$2-5, and 1973 to 1975-US$1. Values roughly double in Brilliant Uncirculated condition.
