This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

Example Input: Passage: In November 1944, after Greece was liberated from Germany, old drachmae were exchanged for new ones at the rate of 50,000,000,000 to 1. Only paper money was issued. The government issued notes of 1, 5, 10 and 20 drachmae, with the Bank of Greece issuing 50-, 100-, 500-, 1000-, 5000-, and 10,000-drachma notes. This drachma also suffered from high inflation. The government later issued 100-, 500-, and 1000-drachma notes, and the Bank of Greece issued 20,000-and 50,000-drachma notes. Third modern drachma coins The first issue of coins minted in 1954 consisted of holed aluminium 5-, 10- and 20-lepton pieces, with 50-lepton, 1-, 2-, 5- and 10-drachma pieces in cupro-nickel. A silver 20-drachma piece was issued in 1960, replacing the 20-drachma banknote, and also minted only in collector sets in 1965.  Coins in denominations from 50 lepta to 20 drachmae carried a portrait of Paul of Greece (1947–1964). New coins were introduced in 1966, ranging from 50 lepta to 10 drachmae, depicting Constantine II of Greece (1964–1974). A silver 30 drachma coin for the centennial of Greeces royal dynasty was minted in 1963.  The following year a non-circulating coin of this value was produced to commemorate the royal wedding.  The reverse of all coins was altered in 1971 to reflect the military junta which was in power from 1967 to 1974. This design included a soldier standing in front of the flames of the rising phoenix.
Question: What year was the non-circulating 30 drachma coin issued to commemorate the royal wedding?

Example Input: Passage: The oldest securely dated tin bronze artefact are found in the heart of the Balkans in Serbia. A tin bronze foil from the Pločnik  are dated to 4650 BC. The foil are not the only tin bronze artefact from the fifth millennium BC. 14 other artefacts from Serbia and Bulgaria are dated to before 4000 BC. The recent discoveries indicate that early tin bronze was more common than previously thought, and developed independently in Europe 1500 years before the first tin bronze alloys in the Near East. The production of complex tin bronzes lasted for c. 500 years in the Balkans. Shortly before the end of the fifth millennium BC, there are no longer evidence for production of tin bronze. This coincides with the collapse of large cultural complexes in the Balkans.Tin bronze would be reintroduced to the area again some 1500 years later.
Question: What kind of tin bronze artifact is found in Serbia?
Example Output:
span
