Anyways, that sounds like a pretty fun experiment. I wonder if it's going to inspire new collectors...?

We did an experiment in high school chemistry back in the 60's where we had to determine the percentage of silver in a dime. This definitely destroyed the dimes.

I would be talking to the police, dean, or principal or someone if this happened to me. A studnet should never be asked for his property for a lesson. Banks exist and he/she can go find their own coins to use.

Quote: I would be talking to the police....... The chemistry teacher sounds like he is just one clueless man who really needs some help from someone knowledgable. If I was Left, I would be happy to help the teacher or simply say say sorry and give him information as on where to buy the coins, how much it will be, etc.

 Shadz response seems a bit excessive....imo. Likely the teacher has no idea as to the of the cost of dateless Buffs. Sounds like a great/fun experiment....Maybe you could get the class excited about coins by asking to give a brief history of the test subject?

He could always go to a local coin shop, buy some junk silver coins he needs, do the experiment and then sell the coins back to the shop for only a minor loss.

"He will probably give them water, maratic acid, hydrogen peroxide and a few other chemicals so they can mix and match until they find a substance that works best to dissolve the outer thin layers of metal therefore revealing the date :)"
Take a baby food jar of vinegar & see who has better results. All in all, right intention, wrong direction. Have fun!

Friends don't let friends clean coins! ;) Seriously that is kinda messed up that he would even ask. Tell him to go buy some junk silver somewhere else.

I think some of you guys are being just a little too harsh on the chemistry teacher. I mean, you can ask for help if you want to. Be that guy who really wants to do a fun experiment but is clueless about where to get the materials and really just needs help. It is really the OP's choice how to react to the teacher's ask for help.

Not sure of your school system but at one time I was a Chem teacher in a Junior college. IF I would have asked anyh student for personal property of any kind, I'm sure that would have ended my stay there. As already noted, IF this teacher has the slightest amount of brains, could simply go to any coin show, coin store, jewler, pawn shop, etc. and purchase such items. Requesting anything personal from a student is not only not to smart, but could be a problem in the future if that student's house was robbed. Already this is a bit suspicious even knowing and pubicizing personal info about a student.

Sheesh...so hard on the poor teacher....but the way I view it is tue oppurtunity to gain the kids interest in the world of coins.....also I've known him since freshman year and I'm a junior now....to clarify I made this postbasking for advice...if he asked for something I didnt want to do I would have said no straight up

Left... good luck with the experiment. Any teacher that is willing to expand knowledge is on the right side! I hope you post results from the experiment and the reactions of your classmates to a beautiful coin.

First thing I want to do is appologise..
It really seems this teacher is trying new and different approaches to teach the curriculum and make it interesting for all...
Professionally my biggest contention is that he approached you to USE your coins ... it's just too much of a grey area for myself personally.
Clearly you feel this teacher has the best interests at heart... so to your original question I suppose it would all depend on the what the experiment what... sometimes 40% silver would be fine.. but for most things if you're testing silver the higher the silver content the better the results.. so I would recommend 90%...
The blank date buffalo experiment also sounds intriguing... what ever the choice is between you and the teacher please keep us posted as to what was taught and how the coins were used...

Quote: my biggest contention is that he approached you to USE your coins ... it's just too much of a grey area for myself personally. This is my problem as well, you don't abuse the power of authority to even ask something like this for materials that may have value to your students. I remember in elementary school a teacher had a record palyer and it broke from normal use before she was going to need it for a class thing that came with a record to be played along with it. She asked anyone if they had one at home to borrow, and being the only one that did, I just said "NO. I don't have one." Even at that age I knew that trust must be earned and there was no guarantee that it would be returned after a day of exposure to that kind of jungle it would even work after. There is 2 things a teacher on any level should do if they need materials for the course, provide them or ask EACH student to bring their own. Obviously you cant ask every student to bring in Buffs. To provide them their-self the teacher should requisition the materials in advance from the school, or go buy them their self! There is just the respect factor in the whole thing. You are a teacher with a paying full time job, and you want to try something new and cannot provide the materials yourself or convince the school to put it in the budget? 40 nickels to a roll, that is enough for a whole class right? $2 cost of materials. the most offensive part of this is the abuse factor by this teacher: Quote: He just walked up to me and asked me if he could borrow 20 silver coins Hey why doesn't he just ask to borrow the class members credit cards too while he is at it! If he really needed silver coins that badly, everyone knows about ebay, so he should have been going on and bidding on some for what he could afford to do the thing with. Teacher: Hey student I know you have some precious metal, can I borrow it form you to use chemicals on it?  How are you going to instill respect for others in the classroom if the teacher doesn't even show respect to the students. The who line above just rubs me the wrong way.
