ONE CENTAVO (1903-41) Diameter: 24 millimeters Weight: 40 grains Composition: .950 copper, .050 tin & zinc (1903-41) Value depends on condition or grade. Don't have my Standard Catalog of World Coins with me but will try to post a $ range later. On a retail site I found 2 listed: $0.75 in the grade of AG; $4.00 in the grade of XF. The PCGS Set Registry assigns a weight of 2.00 to the 1933-M One Centavo.
That metal composition is also called bronze The coin is fairly common and as stated previously, the value depends on the grade. 1933M One Centavo F= 0.25 VF= 1.50 EF= 3.00 UNC=20.00 BU= 35.00
