Sorry, girls, but I need to VENT!

I just got a totally snotty email from a new-ish Etsy seller telling me that my Antique US coin pendants were all totally illegal and 'she thought someone should tell me'.
For the record, since I'm sure not everyone is all up on their US currency laws, it is illegal to FRAUDULENTLY alter currency that is CURRENTLY IN USE. I'm fine under that definition two ways: 1) The coins I use are out of circulation or antiques and 2) I'm not altering them in an attempt to counterfeit (ie: making a $10 bill look like a $100 bill = illegal, thats the 'fraudulently' part).
The email set me off because it was snotty, and it assumes that I've been selling on Etsy for almost 2 years without ever bothering to look into the laws, which OBVIOUSLY I did before I ever listed any coin jewelry. My day job is at a law firm, I spend most of my waking hours surrounded by lawyers, TRUST ME I got lots of advice on this before setting out. I do make an effort to use only out of circulation coins (which is pretty easy, now that most European currency is out of circulation) and even if I do sometimes wind up with a coin that is currently in use, the fact that I'm not altering with an aim to counterfeit still makes me fine under the law.
Sorry . . .I warned you guys that this was going to be a vent! I'm not going to bother writing back to the other seller (cause, like I said, SNOTTY!) but her email really had me ticked and I had to have my little freakout somewhere, so in the event that you've read this, THANKS for listening

So, I sold at my first craft fair on Saturday. FUN! I didn't sell much (my items were a little higher priced than many others) but in the days just after the fair I sold 3 items to buyers in So. California, so I'm thinking the fair was helpful on the promotion front, at least

Here's a photo (with my fiance behind my table)!
