I've never seen 51's used as a term. It may have siginifance, like 73's does, going back to the telegraph era. 73 has morphed over the telegraph era to become "Best Regards", which is why it's still commonly used.
51's is very similar to 73's. It is simply in another language (Latin I believe). When translated back to English the closest translation you get is "wishes". In C.B. radio it started becoming widely used by Single Side Band radio clubs due to a C.B. radio magazine columnist signing off his DX report with 73's and 51's. wishing you "best regards"(73's) and "good DX"(51's). In amateur radio there is a rare German communications guide where it is documented and it means "take care" and don't get caught!(by the "radio police"). That was the closest translation I could get from a German radio operator belonging to a club called the European Radio Group out of Witten, Germany. There is also, from this communications guide the term "55" meaning "lots of success" and "66" meaning God bless!... hope that helps
73!
