1) You don't need 2 threads on the same topic 2) Those pictures are not nearly clear enough to be able to provide an accurate grade 3) Those are both common coins that can easily be found in a world coin bin 4/$1. I provided you a link in your other thread.
@spirityoda you're good with world coins. Can you explain the difference between OP’s coins and the other.
Here are the amounts minted for your 2 coins per each year. 1960 - 99,144,000 1965 - 154,720,000 There is no reason for them to be worth $250.00 (Unless they were minted on Copper Nickel planchets as mentioned on the next posts) https://en.numista.com/catalogue/pieces953.html
Here is the page he is referencing. Most likely his coins are the common ones worth almost nothing. Mac retail in VF they are listed at .50 cents. But even that is high. Again agree with Paddy. These are common 4 for a dollar junk bin coins. https://www.ngccoin.com/price-guide/world/mexico-estados-unidos-mexicanos-5-centavos-km-426a-1960-1965-cuid-1116306-duid-1417915
In 1960, 1962 & 1965 a handful of coins made from a copper-nickel planchet were minted and found their way into circulation (coins during this period had a brass composition). Some have classified these coins as trial pieces while others say it is a true unique circulating type coin. The pieces listed at $250 are the copper-nickel planchet variety I believe and very few have been graded.
according to my 2019 Krause world coin catalog Mexico, KM#426, metal-bronze. size-20.4mm 1960 - mintage-99,144,000 grade/value VF20-$0.10 cents XF40-$0.15 cents MS60-$0.50 MS63-$0.75 cents 1965 - mintage-155,720,000 grade/value XF40-$0.15 cents MS60-$0.25 MS63-$0.35 your coins are super common. Both your coins combined are probably worth 50 cents - $1.00 ------------------------------------------------------------------------------ KM#426a size 20.5mm metal- copper-nickel 1960 VF20-$250 XF40-$300 MS60-$375 1965 VF20-$250 XF40-$300 MS60-$375 must be size 20.5mm and be copper-nickel.
Both your coins look bronze color so they are thee obviously the very common coins. here is a link of the copper-nickel silver/gray color version on a ended Ebay auction: https://www.ebay.com/itm/1965-Mexico-5-Centavos-Rare-Pattern-Coin-Struck-In-Copper-Nickel-/183795614710?hash=item2acb1283f6:g:ycQAAOSwcyVcyodJ&nma=true&si=MtCKZabK1FFrFw3XIxj1%2FV0GQVs%3D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557 pics from it... These are rare hence the high price tag.
