Johann II of Nassau, Archbishop of Main?

I could have a replica coin of Johann II of Nassau, Archbishop of Main, its gold weighing 3.5 grams.  Is it rare? Any info would be appreciated thank you

I would expect a replica to sell for close to bullion value.  

Johann II goldguldens are fairly plentiful in collectible grades, so genuine ones sell at prices that are quite reasonable for medieval gold.  

Some examples (he made several types):
