Nazi-era (1936 - 1939) 5 Reichsmark coin, 3 cm in diameter and composed of 90% silver and 10% copper. The reverse shows the head of Reichspräsident Hindenburg and is marked "D" (to the left of Hindenburg's neck), which means that it was coined in Munich (A = Berlin, B = Vienna, D = Munic, E = Muldenhutten, F = Stuttgart, G = Karslruhe, J = Hamburg).

German 2 Mark coin with the head of Konrad Adenauer (1876-1967), the first Chancellor of (West-)Germany after the war. About 27 mm in diameter.
French 1 Franc coin, dated 1942. It says Etat Français (French State) on the reverse, no longer République Française (French Republic), for obvious reasons. The Etat Français was another name for the Vichy régime in the southern part of France. I don't know whether these coins where also used in the northern part occupied by Germany. The words "Travail, Familie, Patrie" signify what was important to the propaganda at the time: work, family, fatherland. About 23 mm in diameter.
Two French coins of the inter-war period. The bigger one (1939) is 27 mm, the smaller one (1923) about 21 mm. The hole in the piece of 10 cents was factory made and is to be found in all similar coins (i.e. it was NOT punched by a private owner, for example to wear on a necklace). Opinions vary as to the reason for the hole. Some say it was to save metal, others mention an old tradition of wearing coins on a string instead of carrying them in a purse, especially in the French overseas colonies.
Belgian 5 cents coin, 1942. With the monogram of King Leopold the 3rd. 18 mm.
Roman "as" of about 22-23 AD, struck during the reign of emperor Tiberius. The obverse says DRUSUS CAESAR TI AUG F DIVI AUG N and shows the head of Drusus (the younger), Tiberius' adoptive son. The reverse says PONTIF TRIBUN POTEST ITER and S(enatus) C(onsulto).
Copy of Roman sestertius with the head of emperor Caligula (reigned from 37-41 AD). The reverse shows his three sisters, Agrippina, Drusilla (the one he had an erotic relationship with) and Julia.
Roman sestertius of about 41 AD with the head of emperor Claudius. The obverse says CLAUDIUS CAESAR AUG(ustu)s P(ontifex) M(aximus) TR(ibunicia) P(otestate) IMP(erator). The text on the reverse reads EX S(enatus) C(onsulto) OB CIVES SERVATOS. Claudius is thus said to have saved the citizens of Rome from his evil predecessor, Caligula.
Roman Follis of emperor Constantius I Chlorus (reigned from 293-306 AD). At the time, there were two emperors (Augusti) to rule the vast empire, each having a second-in-command, a Caesar. Constantius I was Caesar from 293 to 305 and promoted to Augustus in 306. His son and successor was Constantine the Great. This coin may have been minted in Trier (Germany), but I'm not sure.
Small Roman "follis", presumably with the head of emperor Constantine the second (reigned from 337-361 AD)
unidentified small coin, I don't even know whether it's Roman or not. If you look carefully, you can discern a head looking right on the reverse of the coin.
