Let's see what we've got there. All of them are "cheap" (less than a dollar) as far as I can tell, but it's a nice "starter" world coin collection.
Row 1 Coin 1: not sure, but I think it's Egyptian; would need to see the other side.
R1 C2: Pakistan; the square one is a 5 paisa, I believe; reverse should have a sailing ship with a number "5" superimposed on the sail.
R1 C3: Ceylon (Sri Lanka) 2 cents 1971.
R1 C4: Pakistan 10 paisa.
R1 C5: China (Taiwan) 10 cents 1955.
R1 C6: Yugoslavia. 'Fraid I can't tell more than that without the other side.
R2 C1: Pakistan again; the small 8-point scallop should be a 2 paisa.
R2 C2: the lion-and-sun symbol is of pre-Revolutionary Iran, but I'm having difficulty matching it to a specific coin; need other side.
R2 C3: China (Taiwan) 50 cents.
R2 C4: Yugoslavia 1 dinar 1953.
R2 C5: Finland 1 penni 1970.
R2 C6: Norway 25 ore.
R3 C1: Algeria 5 centimes 1970. The coin commemorates the beginning of a "Four Year Plan", hence the double-date.
R3 C2: United Arab Republic, but I can't tell whether it was struck by the Syrian or Egyptian half of the federation. I think it's an Egyptian 2 milliemes 1960, but I'd need to see the other side to confirm, which if I'm right should look like R6C5.
R3 C3: Japan 1 yen, Year 46 of emperor Hirohito (= 1971 AD).
R3 C4: Israel 5 agorah, Year 5721 Jewish Calendar (= 1961 AD).
R3 C5: much the same as R2C5.
R3 C6: Algeria 1 centime 1964.
R4 C1: See R3C5 and R2C5.
R4 C2: Bhutan 1 pice, undated but known to have been struck in the period 1951-1955.
R4 C3: Iran, 1 rial dated 1351 Iranian Solar calendar (= 1972 AD).
R4 C4: Nepal 10 paisa, dated 2024 Vikramasamvat calendar (= 1971 AD).
R4 C5: see R4C1, R3C5 and R2C5.
R4 C6: Ceylon (Sri Lanka) 1 cent 1963.
R5 C1: Pakistan; this rim is only to be found on the 2 paisa, I believe.
R5 C2: Saudi Arabia, I think it's the 1 ghirsh 1957/8, but I'd want to see the other side to confirm.
R5 C3: Pakistan 5 paisa.
R5 C4: Something flat. Anything on the other side?
R5 C5: Algeria 2 centimes 1964, a partner for R3C6.
R5 C6: see R4C5, R4C1, R3C5 and R2C5.
R6 C1: Saudi Arabia, a later design than R5C2; probably a 10 halala from the 1970's.
R6 C2: Iraq 5 fils 1975.
R6 C3: Greece 50 lepta 1970.
R6 C4: Japan 50 yen, Hirohito year 31 (= 1956 AD).
R6 C5: Egypt 1 millieme 1960. Presumably a counterpart for R3C2.
R6 C6: see R5C6, R4C5, R4C1, R3C5 and R2C5.
R7 C1: Nepal 2 paisa. Need to see other side for date.
R7 C2: Syria 5 piastres 1971.
R7 C3: Ethiopia 1 cent, struck with frozen EE1936 date between 1944 and 1975.
R7 C4: Jordan; probably the 5 fils, but it would say in English on the other side what the denomination was.
R7 C5: see R6C6, R5C6, R4C5, R4C1, R3C5 and R2C5.
R8 C1: Guernsey 1/2 new penny 1971.
R8 C2: Morocco 5 santimat 1974.
R8 C3: Sudan 5 millim 1972.
R8 C4: Algeria 5 centimes 1974. This was the next Four Year Plan (see comment on R3C1).
R8 C5: Pakistan 1 paisa 1974.
R9 C1: another Pakistan 1 paisa, older than R8C5; date is on other side.
R9 C2: Saudi Arabia 1 halala, Year 1383 Islamic calendar I believe (= 1963 AD).
R9 C3: Saudi Arabia 50 halala Year 1397 (= 1976 AD).
R9 C4: China (Taiwan) 10 cents, circa 1970's, date on other side.
R9 C5: see R7C5, R6C6, R5C6, R4C5, R4C1, R3C5 and R2C5. You did realise these were all the same type of coin, I hope?

Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
