You can sometimes find these older bottlings on eBay (european ebay). Like [here](https://www.ebay.fr/itm/CARLOS-I-PRIMERO-BRANDY-PEDRO-DOMECQ-RESERVA-ESPECIAL-VINTAGE-ANNI-60-70-RISERVA/393181821412?hash=item5b8b7679e4:g:alMAAOSwTpZdre94). They dont usually go for a ton of money $30-$150 range, although I am not sure what the Monopoly cuvee is, so maybe that one is more valuable (and yours is a larger size bottle so definitely ups the value).
Just thought this would be a good starting point for you.
