Oscar, If you find a dollar bill whose portrait features Washington without his famous wooden false teeth, or one wearing his famous coonskin cap; well, then you've got a winner!
There are some people on here that are very courteous, some seem to lack any tact at all, and some have lower amounts of patience. A thick skin is definitely required for this site. I find it better to just ignore the things said that are rough, and to enter into conversations with those that you appreciate. If someone says something and is ignored, they usually stop posting along their line of action. Either they get it, or don't get anyone to joust with and move on. Welcome to CT Roberto and Oscar.
IMO, it appeared as the OP was not a native English speaker. I try to have a lot more patience when answering them. It would be impossible for me to make a coherent post in Spanish or another language, so they automatically get my respect. I believe a more significant problem is the use of “Textlish”. No punctuation, creative spelling and confusing points makes some of these posts nearly impossible to comprehend. I’m not talking about a misplaced word or occasional run on sentence (heck, my posts are littered with missing words, incomplete editing and bouncing tenses), I’m referring to a post that sound like you’re talking to your BFF after school. As far as I’m concerned, numismatics is still a scholarly pursuit and some basic level of communication is required. If you can't convey your question to the group in the same way you would ask a teacher or professional, then maybe you should reconsider posting and not get bent out of shape when you're called out
