The Latin phrase "Dei Gratia Regina Elizabeth" translates as Elizabeth, queen by the grace of God. This phrase (or an abbreviated version, D. G. Regina) appears on all the coinage of the British Commonwealth, therefore it does not identify a specific coin. I don't even know what country it is from, let alone what its denomination is. Furthermore, even if I knew exactly what coin you were talking about, the value varies tremendously depending upon the condition of the coin. Most coins from 1958 would have no value to a collector unless they were in extremely good condition.

DEI is Latin for God. It will appear on many British coins and coins of many of the British Empire/Commonwealth countries. The full, unabbreviated legend for a 1958 (Elizabeth II) coin would read "ELIZABETH II DEI GRATIA BRITANNIA OMN REGINA FIDEI DEFENSOR" meaning - "Elizabeth II by the Grace of God, Queen of all the Britains, Defender of the Faith". Depending on the coin and country, it would often be shown very heavily abbreviated as "ELIZABETH II DEI GRA BRITT OMN REGINA F D", or even "ELIZABETH II DEI GRATIA REGINA" with "FID DEF" on the reverse.
You fail to specify what type of coin you refer to. The only gold British coin minted in 1958 was the Sovereign.
