I saw a fake damier some months ago and I was able to tell w/in seconds. It looked wrong and it was a style that was never done. I saw a fake damier key holder and from far I thought it was real bec. it was in her hand and I couldn't really see it, just saw the checkered pattern, and then as soon as I was w/in a few feet away from her I knew it was a terrible fake.
When I wear my mono speedy 30 I think some people have thought it was fake bec. it's light in patina still. I can sort of relate to you not wanting people to think your bag is fake. I would get a damier speedy 30 if I were you and not worry about it. I think the mini lin is beautiful and not worn everywhere either. I've only seen one irl at the dmv, lol. But the other thing about the mini lin is that it's different and some people who are completely unfamiliar w/ it might then think your bag is fake if that is something that bothers you. I know plenty of people that only know about the regular monogram and know nothing of the others, vernis, epi, damier, mini lin so they either think those are fakes or just not LV. My mother's helper who knew nothing about LV other than the regular mono canvas is how I figured all this out. I would show her bags, an epi and she would say, "that's not LV," and then I'd show her a vernis and she'd say, "I would think that's fake", lol. She's now well educated in LV for a 12 yr old girl, lol.
