These 40 reis coins were issued by King Joao of Portugal between 1811 and 1825. It is very difficult to find well preserved examples, and condition means a great deal to value. The 1815 date is rare and there are a few other nuances described below. Here are typical catalog values for all dates except 1815:
worn: $8 US dollars approximate catalog value
average circulated (like our picture): $75
well preserved: $200
If you have the rare 1815 date, multiply the values above by three. Further, note that there are two designs for the crowned globe on the back of the coin. One is a 'tall globe' and one is a 'round globe.' The tall design generally appears on coins dated before 1820 and the round globe appears after that. But, if you can find a tall globe on a coin dated 1821 or 1823, then you have a more valuable piece, as follows:
We received an inquiry via e-mail about this unusual coin. Shailender sent us the photograph at the left, but no other information except that it is an ancient coin from India.
There is much interest in these coins and we have prepared this page with up-to-date information. This page covers:
Your coin must be dated 1945, Tolar. The United States of Mexico (Estados Unidos Mexicanos) started issuing coinage in 1905.
Most dates of this coin are worth very little -- less than $1 US in worn condition. The piece shown in the picture has a numismatic grade around Extra Fine (XF) to Almost Uncirculated (AU); it is well preserved. If Tolar's coin is in as good shape as the picture, the $8 figure is a good estimate of catalog value. Here are typical values for these coins:
Most people think that old fashioned wheat-backed Lincoln cents (pennies) are very valuable. In fact, millions and millions of them were minted and all but a handful carry no significant value. When worn or in average circulated condition, most wheaties are worth a few cents each. Even in fully uncirculated condition, coins dated after 1933 are worth a few US dollars each. For most coins before 1934, here is how the catalog values run:
LINCOLN CENTS DATED BEFORE 1934 (except as noted below):
Hi Paula -- Your half sovereign derives its value from its gold content. A half sovereign contains 0.1177 troy ounces of pure gold, and a full sovereign contains 0.2354 ounces.
Given the current value of gold, approximately $1340 US dollars per troy ounce at this writing, the value of Paula's coin is 0.1177 x $1340 = $158. That is the base value of your coin. Tomorrow it will be different, because the value of gold changes every day. Look it up at kitco.com.
This is a silver medal by sculptor András Kiss Nagy celebrating Ignaz Philipp Semmelweis who was a Hungarian physician known as an early pioneer of antiseptic procedures. Described as the 'savior of mothers', Semmelweis proposed the practice of washing hands with chlorinated lime solutions in 1847 while working in Vienna General Hospital's First Obstetrical Clinic. At that time, doctors' wards had three times the mortality of midwives' wards.
The medal is worth its weight in silver plus a collector premium. The medal contains about one-half troy ounce of the precious medal, so at, say, $20 US dollars per ounce silver, the silver value would be $10. Look up the current value of silver at kitco.com.
