Error Coins

Ive been collecting coins for a while but I still don't know the going prices for errors.  If anyone can give me a general idea I would really appreciate it.  #1 2020P Marsh-Billings-Rockefeller for Vermont.  Not sure how this happended, strike error?   #2  !986D Washington Quarter struck on a penny?  #3 2015P North Carolina struck on a penny?  Are they worth more than a quarter?  Thanks for your help.

Just damaged quarters

Maltreated coins, nothing else.

#2  !986D Washington Quarter struck on a penny?  #3 2015P North Carolina struck on a penny? 

Your coins weigh around 5.5 g., how could they be struck on a penny planchet weighing 2.5 g.?

You're probably mislead by the colour but that brownish colour comes from environmental damage.

I was just going buy what I've seen on ebay.

Welcome to Numista!

You can ask any price you want on eBay, but if you want to know the value of a coin, you must look at WHAT IT HAS ACTUALLY SOLD FOR.

So, by all means go on eBay and do your research there, because it is the single biggest marketplace for most U.S. coins, but make sure you do an Advanced Seach, and click on the Sold Items button.  Otherwise you will be misled by the scammers who are hoping for a sucker.

Can you please explain environmental damage because they look just like a copper penny to me.  I'm not saying you are wrong I just need a better understanding of how a quarter looks like a penny happened in the environment.  Was it dipped in copper or something?

Copper-Nickel clad coins take on a reddish brown hue when exposed to the  outside elements.
