Sure enough, Jan. You have a 2 filler coin from Hungary. The coin in the picture is in beautiful shape, almost uncirculated, with a pretty patina that coin collectors call red-brown. If your coin is in average circulated condition, it looks more like a garden-variety US penny with a normal brown color. Coin collectors will eagerly pay premiums for copper coins with red-brown color. That said:
NEVER CLEAN YOUR COINS. CLEANING RUINS VALUE.
When someone cleans a copper coin, the surfaces turn a bright orange. Coin collectors will not buy orange coins.
Some of these coins were minted in iron, as well as the more common bronze.
Now, down to business ...
The catalog values of these 2 filler coins from Hungary vary widely. There are *common date* coins, *better date* coins, and then there are some high-priced *special dates*. We will run though each of these, specifying catalog value for average circulated and fully uncirculated examples.
Be sure you understand what 'catalog value' means. Use our Important Terminology link for this purpose.
