How to Identify the 2 Koruny
A collector's checklist for the Czech 2 Kč: its eleven-sided shape, lion obverse, Great Moravian jewel reverse, size, metal, mint marks, and common look-alikes.

Start With the Shape
The fastest diagnostic is the outline. A genuine 2 Koruny is eleven-sided (hendecagonal) with gently rounded corners, unlike the round 1 Kč and 5 Kč that share the same coin family. Combine that with a small diameter of about 21–22 mm, a light weight of a few grams, and a smooth, unlettered edge to confirm you are holding the 2-koruna piece and not a neighboring value.
Read Both Sides
The obverse should show the double-tailed Czech lion, the state title ČESKÁ REPUBLIKA, and a four-digit year, framed by a patterned geometric field. The reverse should carry a bold 2 with Kč and the round, jewel-like ornament derived from Great Moravian metalwork. If the value reads in haléř, in Czechoslovak legends, or in a different currency name, you have a different coin.
Check Metal and Mint Mark
The coin is a pale silvery base metal. Because these small Czech denominations use a nickel-plated steel core, a real one is attracted to a magnet, which is a useful authenticity and sorting test. Then look for a tiny mint mark within the design. Early 1993 pieces can bear the marks of the mints that produced the first Czech coinage before regular striking settled at the Czech Mint in Jablonec nad Nisou, so the mark together with the date helps pin down where a given example was made.
Rule Out Look-Alikes
The most common confusions are with the round 1 Kč and 5 Kč coins, with older Czechoslovak koruna pieces, and with early Slovak koruna coins from the same 1993 currency split, all of which differ in shape, legend, or emblem on close inspection. Corrosion or heavy wear can obscure the year and mint mark, so judge condition before assuming a date.
Authentication Cautions
This is a common circulation coin, so the real task is correct attribution rather than fraud detection. Be cautious of polished or artificially toned pieces marketed as scarce; genuine value here rests on original surfaces, an accurate date, and legitimate mint-set provenance rather than surface shine. Avoid cleaning the coin, since bright original examples are worth more than hairlined, scrubbed ones.
Frequently asked questions
How do I tell the 2 Koruny from the 1 and 5 koruna coins?
Shape is the giveaway. The 2 Koruny is eleven-sided, while the 1 Kč and 5 Kč are round. Confirm with the value shown on the reverse, either 1, 2, or 5 beside Kč.
Do the mint marks matter on this coin?
For everyday value, little. But for collectors the mark and date can identify early 1993 issues struck before regular production settled at the Czech Mint, which adds interest to an otherwise common type.
Can I use a magnet to check it?
Yes. These small Czech denominations are struck on a nickel-plated steel core, so a genuine 2 Koruny is drawn to a magnet. It is a simple, non-damaging test that also helps sort the coin from non-magnetic white-metal pieces.
Is a worn or dirty example worth cleaning?
No. Cleaning modern coins usually harms them by leaving hairlines and unnatural color. Collectors prefer original surfaces, so leave the coin as found and judge it on shape, date, and mint mark instead.
