Portugal 10 reis Josephus (Jose I) weight and diameter don't match

Hi,

I got this low ball dateless coin from bigger lot. I found similar coin type (km 243) from Numista and other databases, but weight (10g) and diameter (33mm) are like from previous 10 reis type (km 227, Joannis V/Joae V).Is there a hole in the catalog or am I rich now?

A picture is fundamental.
From King Josephus there are also similar 10 Reis coins from Angola, Azores & Brazil and all have a date.

Thanks for the info. This is a real low ball, the date is just worn out:

It is a normal coin, KM#243
The date and most of the coin has gone...
     

Ok, thanks monge. This is a very good canditate to ugly coin contest
