Yeah, benmoore, it's that double-headed eagle that helps identify this Austrian coin. Of course it could be Hungarian, Russian, or even German, but it turns out your coin is from Austria. The 1 heller and 2 heller look the same except for a large 1 or 2 on the side with the 'apple' pattern. With no inscriptions, it is often difficult to figure out this coin without seeing a picture.
Typical catalog values are the same for both 1 heller and 2 heller, as follows:
worn: less than $1 US dollar approximate catalog value
average circulated: less than $1
well preserved: $3
fully uncirculated: $6
Remember these are catalog values. See our Important Terminology page for an explanation of what 'catalog' means.
There are a few better dates for these coins that are worth more than the common dates shown above. Here they are:
1892: catalogs at $75 in average circulated condition
1898 and 1899: catalog at $10 in average circulated
1892: catalogs at $100 in average circulated condition
1901: catalogs at $5 in average circulated
In addition, there is a nuance in 1 heller coins dated 1916. The inset shows a different shield on the eagle's breast. This shield shows up on some 1916 hellers. If you have a coin with the design in the inset, rather than the one in the main heads-tails picture, you have a more valuable piece. Figure $15 catalog value in well preserved condition, and a $25 in uncirculated.
Double headed eagles also appear frequently on Hungarian and Russian coins (like this cool yellow-on-red Russian coat of arms), as well as other countries in eastern Europe, but the old Austrians really liked the symbol. According to Wikipedia it has origins in the Byzantine and Holy Roman Empires, where the two heads represented dual sovereignty of the emperor: he ruled both as church and state.
