This is an interesting series of copper coins, Peter. I like the design, it certainly is an eye-catcher. The four denominatios addressed on this page have all the same lion, tablets, ribbons, and crown pattern, but their sizes and dates of issue are different. The non-lion side has the monogram of the ruler:
Leopold I: 1831 to 1865
Leopold II: 1865 to 1909
Albert: 1909 to 1934
The values range from a few US dollars to a several 100 US dollars, and even over $1000 for well preserved coins. But, since your coin has a hole in it, Peter, the value goes way down, to essentially zero.
For this page, we first summarize sizes and dates, then catalog values are shown further down the page, with common date coins listed first, then special, more valuable, dates. This page applies only to coins with the lion and tablets pattern shown.
1 Centime: 17 mm diameter, 1832 to 1914
2 Centimes: 22 mm diameter, 1832 to 1919
5 Centimes: 28 mm diameter, 1811 to 1861
10 Centimes: 33 mm diameter, 1832 to 1856
The secondary picture shows the large A monogram for King Albert.
Most of the dates in the series are what are known as common dates. There are a few better dates, but most coins are common. There are also quite a few special minting varieties of these coins, but such variations are beyond the ken of CoinQuest. If you have one or more of these coins in good condition, i.e., with only a little wear and no scratches, stains, spots and the like, it might be worth searching out a coin dealer or knowledgeable collector to get an accurate, first-hand appraisal, just in case you have a rare minting variety.
DO NOT CLEAN YOUR COIN. CLEANING RUINS VALUE.
Below you will find the common date catalog value for each denomination. After that, we list the better and key date values. In general, later date coins (post 1900) are worth less than early date coins. All values are catalog values for undamaged coins. Use the Important Terminology page (link at upper left) to understand how to interpret 'catalog value.'
