Do These 3 South American Coins Look Okay?

[beacon]

I came across today at a pawn shop that has these 3 gold coins for sale at spot price.

After doing some research, I discovered that the 3 coins are the following:

* 5 Pesos Colombia Gold Coin (7.99 grams total weight and .916 gold purity)



* 1968 Colombia Proof Gold 100 Pesos Pope Paul VI (4.3 grams total weight and .900 gold purity)



* Perú 1/5 Libra Gold Coin (1.65 total weight and .916).



Unfortunately my phone camera does not take great pictures, but obviously the 1968 Colombia Proof Gold 100 Pesos Pope Paul VI is scruffy, with dents, and scratches.

I had an earth magnet with me and none of the coins were magnetic fortunately.

Would it be wise to buy these three gold coins at spot price?

Hard to tell from pics they look cleaned but at spot you have got an amazing bargain these are premium coins

Thank you, yes. I saw the person at the pawnshop using a pencil eraser to clean the coin.

 

Even though the coins are worn and have dents, at spot price I might purchase them. since they are fractional too.

Cleaning then with an eraser has taken some value off them but still worth spot plus 10 on my Opinion probably spot. Plus 20 with original. Lustre
