The metal content of a 1978 drachmai coin would depend on the specific denomination of the coin. The most common drachmai coins from that time period were made of copper-nickel alloy. However, there were also silver and gold coins issued in different denominations.
The 20 drachmai coin from Greece is a silver coin.

There is no Australian 1954 20 cent coin. Decimal currency was introduced in 1966.
You have a coin denominated in drachmai from Greece - the first letter, a "delta", looks a lot like a capital "A" or a triangle, and the "X" is a "chi" and is pronounced as a gutteral "ch" (or, if you can't make that sound, like a "ck"). You'd need to know the denomination (e.g., 5 drachmai or 10 drachmai) and its condition to properly value it, but in circulated condition, it's likely worth less than a dollar - in brilliant uncirculated condition, it could potentially be worth as much as about $5.
