This silver medal commemorates the 80th birthday of Princess Marie of Saxe-Altenburg, wife of George V, king of Hanover. The superb example in our picture comes from Westfalische Auktions gesellschaft fur Münzen und Medaillen oHG, where it sold for 320 euros (about $360 US dollars) during a 2015 auction. Approximate catalog values are:
worn: $100 US dollars approximate catalog value
average circulated: $200
Denmark issued a bunch of 2 kroner coins during the early 1900s, and they all have neat patterns. It would be a worthwhile collecting endeavor to assemble a set of nice-looking examples, one from each of the 12 different patterns. It would not be overly expensive, but it would not be cheap, either.
While early 2 kroners were minted in silver, by the time 1924 came around Denmark moved to aluminum-bronze. Mario's example is in such good condition, it looks like gold. But, alas, it is not.
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):
These are grand old coins, Asher. They come from a time when one cent was WORTH something!
Most Canadian large cents are worth about $10 US dollars in average circulated condition and they rise to about $50 or more in uncirculated condition. These catalog values apply to all dates except as follows. Coins dated 1858 are worth $150 in average circulated condition, and dates 1894, 1898H, 1900 (not 1900H), and 1907H are worth about $25 in average circulated. Finally, coins dated after 1908 are worth only $2 in average circulated condition. See our Important Terminology page for an explanation of what 'catalog value' means.
These coins, minted in stainless steel, not silver as Monique has assumed, generally are worth only a dollar or two US. Some of the earlier dates, before 1962, can bring catalog values of about $100, but only if in fully uncirculated condition. Dates after 1962 are generally not very valuable even in pristine condition.
Use our Important Terminology page to understand what 'catalog value' means. It is an inflated value.
Dates with high catalog values in fully uncirculated condition are:
You have made a common mistake, PAJ. One that has happened before on CoinQuest. Your coin is actually from 1994, not 1894. Look closely at the date. Not only that, it is made from aluminum bronze, which can be easily mistaken for gold. In other words, it is a modern 50 centavos coin from the United States of Mexico (Estados Unidos Mexicanos). It is worth face value.
If you have one of these coins in absolutely, fully uncirculated condition, a keen collector might pay $1 or $2 US dollars to add it to their collection.
You have a nice coin from Bulgaria, Daniel. Between 1962 and 1990 the design stayed the same, with composition and size changing with denomination:
1 STOTINKA: brass
2 STOTINKI: brass
5 STOTINKI: brass
10 STOTINKI: nickel-brass
20 STOTINKI: nickel-brass
50 STOTINKI: nickel-brass
All these coins -- all denominations and all dates -- carry low values as follows:
worn: less than $1 US dollar approximate catalog value
These come in brass, non-precious white metal, and silver. They are modern (post 1948) novelty items sold to tourists. Those made of non-precious metal sell retail for a few US dollars. Silver 'magic coins' are worth their weight in silver.
If you do a Google search on 'Egypt magic coin' you will see that other patterns are used and, sometimes, the coins are stressed and beaten to look like they might be genuine ancient coins. They are not.
