German coin

Good morning 
I have a coin that is causing me problems. 
In fact, the legends are reversed compared to the engravings. 
Would you have more information on this subject?
THANKS 
The coin weighs 5 grams. 
The diameter is 30MM 
Silver metal.

N#230204

Your image is better than the one on numista page.

4 Kreuzers (N#230227) got explanation what those letters mean.

You probably need some HRE coinage reference book to check, if there was coin variant with lettering swapped between obverse and reverse.

Krause has 3 variants for 1621 Numista only 1, so yours could be one of the missing ones with a clover or a lily or a different non KM listed varaiant.
THIS one has a lily and a cross and the eagle is facing left.

I think the point of post was that IO(achim) ER(nst) D G … is on the side with eagle and not on the side with coat of arms.

Could be normal for the coins with two lilies or someone ****ed up a die and didn't want to discard it.

Sometimes Krause groups wildly different looking coins together sometimes it separates them on minutia. Like I said could be one of the 3 variants listed in Krause or an unlisted one. The auction I listed has some further references maybe the type is listed there.

Like I said on Facebook this was during kipper period and for some northern states of the HRE die variations that are not documented are not as far fetched as you would think.
