Are they really so cheap that people are selling them by the bulk on eBay? Or are they fake ones? I got five of each 5 Billion, 500 Thousand, 50 Thousand Zimbabwe Dollars for $11. Are there certain markings on them that I can check to see if they're real (like the US dollars have certain watermarks/lines/etc)?
Most of them are real. Because of inflation, they are cheap. The only real expansive is the 100 trillion dollar bank note. That one now cost sgd 100 dollars.
Be kind to people. Sharing is Caring. Collect what you like and not by the Crowd.
To seek for perfection, it is too painful and there is a very high price to pay. To seek for something comfortable is more easy. To seek for nothing is even more easy.
