As far as buying stuff at a chain store... who cares what they think (IMHO). It's cash... deal with it. They only have to keep them in a cash drawer till the end of the day. However, when going to a mom and pops type place or leaving them as tips (somewhere where the person receiving them may/will keep them for a while)... do you think that others see this as insulting, classy and unique, could care less, or what?
Anyone out there used to be a waiter/waitress before your coin collecting days that may shed some light on this? I ultimately suppose it depends on the individual your leaving it for. Me... I see it as kinda classy. For example... Morsecode's use of those coins... while funny to most of us... is kinda sadly serious. MOST people have NO IDEA what PM's are or even less about other non-conventional forms of US currency (and have NO will or interest in saving ANY of their money). Not to mention their lack of knowledge in the history that is shown on some of these coins. I also see it as classy because MorseC. had to not only earn the money to get those coins, but to go out and find those coins (although I'm guessing he didn't have to look to hard... maybe for the Ike though). So to me... for him to leave those coins vs. leaving just a few simple dollars... is... well... pretty cool to me. Plus... as was pointed out... they may actually save them... so you're encouraging them to save money as well. I dunno...
I know I know... most of the rest of the world sees us already as freaks anyways. I mean... tellers still look at me like I"m trying to score cash to buy drugs or something every time a buy a box of pennies.
