When we participate in the flipping of a coin, the command given is to predict the outcome as "heads or tails." For centuries most American and British coins have featured a bust or profile of a head of state on one side of the coin (two-cent pieces, three-cent pieces, and shield nickels would be exceptions). For the other side, the OED explains with a citation from 1810 that it is called a tail "without respect to the figure upon it."
When the coin flipped comes from another country, however, the terminology may change. When the kopeck above is flipped, the choice is "lattice or eagle." The figure on the obverse is a monogram of the ruler, but to the common people it was viewed as a lattice. Other countries offer other choices:
For a Hungarian it is so obvious to call this game fej vagy írás, “head or script” that he would not believe if somebody told him that no other people says it exactly like this. The Germans say Kopf oder Zahl, the Spaniards and Italians Cara o cruz and Testa o croce, the Poles – just like Russians, and obviously after the same kopeiki – Orze? czy reszka, the Irishmen Head or harps, the Greeks (crown or script), and the ancient Latins Navia aut caput (ship or head [of Janus]), depending on the actual designs of their coins.
What comparable phrases have readers of Neatorama encountered in their home countries?
Addenda from Neatorama readers:
Bojan Zarkovic - Serbians also use "head or script."
Joris Slob - the Dutch use "kop of munt" (head or coin) because the queen is on one side and the number of cents/euro on the other.

Informantxgirl - in Thailand, it's "heads or pinky (koy)" - the "pinky" side showing a building or monument.
Paavo Ojala - in Finnish its "kruuna vai klaava," words borrowed from Swedish ("krona eller klave"). Some people don't know which word means which side.

Tom T - in Portguese it's "Cara ou Coroa" (Head or Crown) - even though there is no crown on current coins.
nadiv - in Hebrew it's Etz (tree) or Pali. "These two terms come for the time of the British mandate over Palestine. The English "heads" was transformed to Etz, even though there's currently no head or tree on that side of the coin. Pali comes from Palestine, the writing on the other side of the coins back then."
