Advice on European coins please

FilamCoins

Was wondering if any of these are interesting. Picked them up at a local auction because they looked pretty. Don't know anything about European coins. Amazing luster and virtually problem free (a few ticks and tiny spots here and there). I hesitate to grade coins I don't know, but 65+ wouldn't surprise me. Are any of these worth slabbing? I'd like to sell them to a collector who can really appreciate them, as I'm not ready to take on Europe yet. What do you think?

1965 Austria 50S
1964 Luxembourg 100F
1965 Czech 25K
1948 Czech 100K
1969F Germany 5M



Thanks

Not only are they interesting but they are beautiful. A real nice assortment of moderns.

Is the German one a proof or an uncirculated?

Hummmm (Don't have anything to compare it to).

Mirror like reflective surfaces with a mild cameo effect (not very high relief). BUT there are a few tiny bag mark like nicks, which suggests business strike.

Man, I forgot how hard (and fun) it is learning about a new series!!!

Unless you can get supergrades like 67 or better they're not likely to be worth slabbing.

Thanks, JJ, I was hoping you'd chime in

The later date German commems never seem to do well, even in very high grades.
Czechoslovakia is generaly a slow selling country despite having some winning designs.
Luxembourg can do OK (not great) but the coin needs to be issued a bit earler.
Any and all post 1918 Austria always dies for me.

Here are some good rules of thumb for common world coins:
Anything from the 1970s and later is not worth it unless you have a shot 68 for business strikes or 69DCAM for prooofs.
From the 60s shoot for at least solid 66s on either proofs or business strikes.
50s and earlier you generally need a 65 to sell well.

Things that are AU/MS liners should be slabbed if there's a chance of receiving an MS grade (many AU looking coins do) and there's a significant price break.

For truly rare stuff certification always helps.
