Thank for your reply, so if they are really fake it is almost good if we look on golden price =) - Can You justify your answer? regards
For one thing the Maria Theresea coin, there is no such coin with that date. And more than anything it's just the look of the coins. I've owned several examples of both of the others and they never look like that.
What you have are fantasy tokens-- they are much too small to be actual gold coin issues. The Netherlands gold 1 gulden, for example, was not an official issue, and if it were, it would have weighed nearly 0.7 gram. Yours doesn't even have a date. Here is an example of a fantasy token (on the right) produced in Mexico. It is 22K and weighs 0.54 gram:
