Counterfeit Forever Stamps

Seller said they were purchased from estate sales across the USA, UV tested and genuine, but I can return if desired. I appreciate the option and completed the return. I then used the full credit as ebay gift card to pay another stamp order (cancelled ww stamp albums).

All of the tagging on the stamps you showed look correct. I compared mine which are purchased directly from USPS to yours. You need to be aware that many of the current issues don't have tagging that appears bright solid green/greenish yellow. The bright solid green one is printed on prephospored paper which usually appears bright green. The others have the taggant printed over the image. On many current issues the taggant can be sparse when observed under magnification or they are on bright paper. As such they are duller green. This is an area I specialize in.
