Check this sand a penny on both sides till it is polished mirror like start with 120 grit then end with 1000 grit.then put some paste on both sides put the penny on the core then atatch the gorb to the slocket.you will have to use a little more force to twist it on but it is nice and snug after and you loose 3-4 deg when i run burn p6 i use to top out at 46 now it fluctuates between 42 and 43

I believe all pennies older than 1978 are copper.
Cept the ones from WWII They are pure steel. But rare. :p

This gain also may just be a result of the increased clamping preasure from having the penny in there

U.S. Lincoln pennies from 1909 to 1942 are 95% copper, 5% tin and zinc.

1943 pennies are all steel with a zinc coating.

1944 to 1946 pennies were made from used WWII cartridge cases which are 95% copper and 5% zinc.

1947 to 1958 pennies are 95% copper and 5% zinc.

1959 to 1962 pennies are 95% copper, 5% tin and zinc.

1963 to 1982 pennies are 95% copper and 5% zinc.

1982 to present have a core of 99.2 % zinc, 0.8% copper and a pure copper coating ( total content is 97.5% zinc and 2.5% copper).

Note: in 1982, pennies were made in both of the above listed compositions.

Coin collecting class 101 is now dismissed.

Break the bank and use an older quarter or half dollar from back when they were Silver. You can also get a modern 1oz Silver Dollar for around $5.00 bigger is better.

If you're going the silver route, 1964 or older dimes, quarters, and halves are made of 90% silver. A quarter would be a good size, but a little thick unless you did a lot of sanding.

Dunno, if you read my earlier post, I already said that pennies minted after 1982 were mostly zinc with just a thin copper plating.

Lucky is right about any of the pennies from the 1970's being mostly copper and they're still pretty easy to find too.

batboy, i must have posted before reading your post, commenting to the one on pennies being steel on the inside. No offense taken though. This tip applies to both socket a and 270, and really any heatsink, not just the orbs, although the orbs need all the help they can get in cooling(man they are pretty though). I would be careful using this though as you are really going to increase the pressure on the cpu, maybe even crack it. Oh, don't try to melt the copper or silver coins, they will oxidize and become useless.
