I would follow Dave's advice on the $5's, the $20's are a large chunk of gold for a beginner...
World gold coins commonly found a little over spot - my personal favourites (note: i'm a bit biased against restrikes, coins over 1/2 Oz. and any gold coins minted after 1945):
UK - 1 and 1/2 Sovereign (i prefer "young head" Victoria coins).
France - Later 20 francs "Angels" (easier to find UNC) and earlier "Roosters" (not restrikes).
Netherlands - 10 Gulden "Wilhelmina" (1st and 4th Type in particular).
Belgium - 20 Francs "Leos"
Denmark - 10 Kroner "Mermaid" (The 20 Kroner of this type carries some premium) and 20 Kroner "Christian".
Italy - 20 Lire (i prefer VE II coins)
Switzerland - 20 and 10 Francs (I like the "Vrenelli" design better than the "Helvetia" one)
Russia - 5 Roubles (Nicolai II)
Germany - 20 Marks (Prussia)
Turkey - 100 Piastres (Ottoman Empire)
Hungary - 20 Francs/8 Florins (i know most people prefer the later 20/10 Korona designs, but i really hate good ol'Francis "I'm a pompous a-hole" pose)
Tunisia - 20 Francs
Peru - 1 Pound (Earlier dates aren't more expensive than later ones and have more "history" in it)
Chile - 50 Pesos (1926 only for some odd reason)
Colombia - 5 Pesos (Early 20's design only)
Mexico - 20 Pesos (Original years)
A dozen of the above coins would be a nice collection IMHO...

On the UK sovereigns, I would recommend checking lots of them if a dealer has rolls of them etc, know your mintmarks, I have picked up Australian, Indian, South African, and Canadian sovereigns just by knowing the mintmarks which are on the base of St. George slaying the Dragon.
I love the roosters, I call them Mariannes because obviously she is my favourite side of the coin.
Russia 10 Rubles used to be economical, but not anymore. 7.5 and 15 Rubles coins are ridiculous now.
Watch for German states other than Prussia, I have purchased Saxony, Bavaria, at not too much over melt. But know your dates, denominations and mintmarks because there are forgeries out there.
With Mexican coins, the 10 and 20 Pesos are real coins, the 2, and 2.5 peso coins are novelties and I don't care for them. I love the 50 Peso, especially in BU, and dated in the 1920's but they have 1.2067 oz of gold so they are pricey.
For difference, look also into Iranian Pahlavis from the Shah's era, and also Saudi Arabian Pounds, both of which I have bought at maybe 5% over melt in the past.
