Nevada License Plates
Nevada changed from embossed to flat plates in 2006 but this only lasted for a few years. Production moved to a new location and Nevada changed back to embossed plates on July 13, 2015. All issues since then are embossed -- small embossed state shape replaced the dot separator at the same time.
The 2013-16 Sesquicentennial plate was never made flat.
The limited-time eight-year "rolling reissue" program removed many flat and unreadable plates from the road only between 2016 and 2023. Older plates replaced first, keeping the same number, "new" embossed plates were mailed with registration sticker after the registrant renewed. See this excellent DMV web page explaining which plate types were affected.

Discontinued plates are no longer issued by the Nevada DMV. The plates shown at the link below are still valid for vehicle registration except for the Big Horn Sheep plate. The original owner of the plate must keep it continually registered to a vehicle or allow it to expire for less than 30 days. The plate may be transferred to another vehicle but not to another person.
Some of the dates the plates were issued are approximate. Most plates with a discontinue date of December 31 failed to maintain the minimum number of active registrations required for charitable plates.
