Without seeing pictures it's very difficult for anyone to give you a good answer. Many factors play in to how much your coins are worth (i.e. condition, scarcity, mint marks, current market demand, etc.)

1 - Take your coin to a local coin dealer (trustworthy ones can be found - shop around). It never hurts to get a second opinion. They will be able to tell you so much more by evaluation the condition of the coins. They will also know the amount minted and what it is going for in today's market.

2 - Try posting pictures on this website (there are many experts here that can help you evaluate it - there also may be people willing to buy if you are trying to sell):

Good luck!

P.S. You should not clean your coins. Most coin collectors see cleaning a coin as the equivalent of stripping down antique furniture and refinishing it.

When cleaning, the surface metal of the coin is often stripped. Anything used to scrub the coin will leave scratches (even 100% pure silk will leave hairline scratches). Most cleaning products will have some type of reaction with the coin's metal and the surface metal can also be removed in this manner.

Your best bet is to leave the coins alone. Cleaning the coin will leave traces - which can be found by the knowledgeable collector - who in turn will not buy the cleaned coin. Also if you ever wanted to send your coin into a grading company, they can recognize signs of cleaning and will send your coin back in a "cleaned" slab (also called a "body bag" in the coin world) - which is usually a greatly decreased value.

If you absolutely must must must clean your coins do not use the method described above as it will react with the metal in your coin. Use 100% acetone (do not use fingernail polish remover!). It must be 100% pure because other additives will react with the coin metal. Place your coin(s) in the solution for several minutes (do not leave in for long periods of time). Rinse your coin(s) in distilled water. Next remove your coins and either pat dry with a soft cloth or allow the coin to air dry (air drying is better as you don't risk scratching the coin with the cloth). NEVER scrub your coins!

I would still advise you to leave your coins as they are. They may not be bright and shiny but that is what most collectors prefer.

Answer 2

First of all it is not a Dragon but an eagle with a snake in its mouth which is the national symbol of Mexico. In the 1300's an Aztec priest told his people when they see an eagle with a snake in its month on a cactus to build a city there, today that city is called Mexico City.The first coin is .720 silver and has.5209 actual silver content., in grades very fine and lower it is worth silver value. On number 2 there are more than one so you need to give denomination.The 10 peso 1978 is made of copper nickel and can be found in dealers World coin boxes for .25 or so. The 1980 Onza is a medallic silver bullion coin and in circulated grades is worth silver value only in mint state it sells for $18-20. Hope this helps.

1. 72% silver 25 pesos of 1968 commemorating the summer olympics in Mecixo City. It's worth $8 in mint and bullion value for low grades. Has .52 ounce of silver. There are two other types of this coin, one with a lower center olympic ring and the other with curved snake tongue and both are worth almost double the normal type mentioned.
2. 72% silver 5 pesos 1953. It's worth $10-$12 in mint, bullion value for low grades. Has .64 ounce of silver. Mo is the mint mark of the Mexican City mint and on one side it's an eagle biting a snake not dragon.
3. Copper nickel alloy 10 pesos 1978. Worth $.50 to $1.
4. 92.5% fine silver bullion coin with nett 1 ounce pure silver. Worth bullion+ in high mint state, and bullion for lower grades.

Answer 4

not worth anything. Mexico revalued it's currency in the 1990s and the coins from the old era are essentially souveniour material. A nice conversation piece or fun for the kids to play with.
