You'll have to excuse the others, but it seems there are a lot of people who come here without doing the research. Part of the reason is because they don't have the patience you did to check things out, and they want a quick and easy answer. This frustrates many of us, and so we tend to assume everyone who asks a question hasn't checked other sources. So give them a little slack, please.
Welcome to Coin Talk. IMO I don't think you offended anyone. I think you misunderstood some of the comments. You don't have to start off a post by saying where you did or did not search. Just ask the question and post photos of the coin. If it's a US coin post it in the US Coins forum. Peace
