Pink Depression glass platter

I have a pair of champagne flutes that match this, but they are packed away so I can't check the note I put in them with the ID. On the bottom are raised letters that say France 30 and glcoloc. I'm getting info that the company is actually Arcoroc and it's called Pink Rosaline. Is there a site that helps date the piece? My mother had a ton of pink & green Depression glass and I wasn't fond of it so I only have a few pieces left. I'm thinking this is much newer, but it was pink so she kept it. She and my Dad had a second hand store and did flea markets so I have a very eclectic attic.

Hi Bev,
This site has some good info about Rosaline. It says 1980's.

But, I just wonder....it doesn't seem to be marked exactly the same way?

 

Well, duh. I had it backwards. It's not glcoloc. That's an arcoroc. I'm kinda slow sometimes. I chalk it up to senior moments. I'm finally old enough to use that excuse. One is listed on Feebay as 1970s and sold for $11. I'll probably spare myself the aggravation of packing and give it to a thrift.

 

I was going to say late 1970s because I received a small set of clear glass with the same markings as a wedding gift for my first marriage.
