The Mexican state of Guerrero issued some coins in 1914-15 that contained 0.3 grams of gold (1 peso) or 0.595 grams (2 pesos); at a weight of roughly 12 grams per peso, this means approximately 2.5% gold.
Siberian copper coins from the 1760s and 1770s contained even less gold (variously given as 90-300 ppm), but 1) I'm not sure how deliberate that was, and 2) at 0.79% silver content they weren't exactly silver coins either.
On the higher end, mid-19th century Japanese "gold" coins were roughly 20% gold and 80% silver.

Canada issued a $100 gold coin that was 14 karat (about 58% gold). A few others in the Caribbean have issued them in 50% gold. A natural gold-silver alloy is called electrum. I am not sure if this is what you wanted to know.

Early Australian sovereigns, the Sydney Mint type (pre-1870), were struck from 22k gold with the remainder silver, rather than copper. Australia had abundant silver mines at the time, but no copper mines, so using locally-made silver was actually cheaper than importing copper. The coins look "paler" by comparison with copper-diluted sovereigns. Because of the high silver content, Sydney sovereigns were actually preferred in trade in India and the Middle East over London-minted sovereigns. Once the Colonial Office in London found out that the barbarians were preferring Australian coins to good British coins, they forced the Sydney mint to stop producing the high-silver sovereigns and conform to the Imperial standard, in both design and composition.

The silver crown was Britain's largest circulating silver coin in the 1800s. It was a bit too large and cumbersome for everyday use, so they briefly considered the idea of issuing a bimetallic coin. But rather than mixing the gold and silver in an alloy, they considered an option very similar in concept to the bimetallic coins actually issued throughout the world over a hundred years later. The coins would have been about the size of a florin (a bit bigger than a US quarter) with a large silver ring surrounding a small plug of gold in the centre. While the idea was eventually discarded due to the increased cost of producing blanks for such coins, some private patterns demonstrating the concept were struck by lobbyist Joseph Moore. Example on CoinArchives. Moore similarly proposed reducing the size of the copper penny by making it bimetallic with a silver core.

The guerrero coin was the one I was originaly looking for. I had no idea there were so many different ones, I kinda like the idea of the electrum coins. I guess that means they just coined the metal just the way they found(mined)it without mixing
Thanks everyone for your your time and knowledge.

While the use of electrum coins clearly evolved from the use as primitive money of naturally-occurring nuggets of electrum, chemical analysis of naturally occurring electrum found in the rivers of Lydia comes up with a composition typically around 70% to 90% gold. The electrum coinage, on the other hand, starts out at a consistent 55% gold and falls to around 40% by the end of the electrum coinages. The consistency of the composition in the coinage at any given time implies that the "electrum" was therefore produced by mixing relatively pure gold and silver, in known proportions. TL;DR: it turns out the coins are actually made of "synthetic electrum", that had less gold in it than naturally-occurring electrum.
