All 1989's where debunked by Dr. James Wiles of CONECA claiming they are RDV-005 back in 2007 plus the font looks correct anyways
The G is deformed. The lettering is sharp and it the G is more rounded and further off the bottom srep than RDV-005. My opinion this is RDV-006 with a deformed G. Maybe partially filled or something like that. Left side is RVD-005, Right side is RVD-006 picture is from error ref.com
I think you guys are right. Maybe the "G" got damaged and just looks funny. The alignment tells the story. Thanks everyone...
