Told I have fakes

[wendypooh]

I have been selling our collection for over 10 years on various platforms. Recently I have had 2 people return pins to me with in a month,  stating they are fake. I have been collecting since the beginning 1998. The pins in question from these two buyers were not fake. No way. I Bought from Disney personally. It gets me to the core. I am sure they were regretting the purchase and just making excuses to send back. But to call me a lyer and down and out fake seller. It hurts. From what I have learned over the years, many pins look different , even though they are the same. Pins are unique and one run of them maybe slightly different from the next. Esp pins coming out back in the beginnning. How do I sell the rest of my collection,  my daughters do not want any longer? I am over ebay and etsy. Any thoughts?
