50's Ford Hubcap ID

Anybody know what year these are? I know I've seen them before, but I'm not a Ford guy. I kinda like them though. How desirable are they?

 

They are 53-54. 56 looked better ,similar but had a smaller crest in the center made out of plastic

 

Thanks! He wants $65 for the set (local CL). They looked in pretty damn good condition. I thought of scooping them up, just cause, not like I need more stuff though. Were they on all models, or just higher end lines? Are they run of the mill or desirable, to anyone other than '53 owners.

 

Those are 54 caps. The 53s are smooth with out the ribs i think. I run the 54's on my truck. 1954 was not a real popular year ford. I gave $20 for a set of 4 with some light dings. The low end customlines ran dog caps and the victorias and other higher end lines had the full caps.

 

Right,,,,,,,54 they are.
