The 1943 Cent Experiment Revisited!

That's awesome!

Fantastic way of having fun with this hobby. Should get an A for this.

The couple misspellings aside I found it very well done and precisely informative. Good job.

Nice job!

The only problem is with the cents, they would have to be nearly identical to make a strong comparison. The only proper way to test would be to buy mint state examples, strip the zinc and then artificially rust the coins to the same level.

What did you use to determine the percent removal? Did you weigh the coins before and after using an analytical balance?

Oops! Thanks for letting me know, SpaceMaNy0! You have failed me for the last time, google spell check (starwars reference)

And, BadThad, I used before photos of each coin. It was had, but I used math (gasp) to roughly figure the amount of rust removed (by using area). I also used the real coins to compare to the before photos, just in case something wasn't shown in hand. For most things, I rounded up. The toothpaste, for example, only removed about 33.45%, but I rounded it up to 35% . An as for the fact that they rust at different levels, I choose out these guys at the LCS to make sure that they all have the same amount of rust... Although, its technically impossible for them to have the exact same... Might need to add that to the "errors" section!

That was a great movie!

Well done COTW!
