Thank you for contacting Mearto with your appraisal inquiry. It is a beautiful gold pin. Such vintage brooches are being offered at auction on a regular basis. The design of the pin is lovely with the horsehead and detailed with a diamond marking the horse eye. It is very elegant and classic. It was probably made in the 1980s where this particular type of animal/horse jewellery was quite popular. It is a type of pin that will attract attention if it came up for sale and both collectors and dealers will be interested. The estimate provided is for a well-advertised specialised online jewellery auction, where I believe the pin has the best chance of realising its fullest potential. However, there is no measurement for the sentimental value you might attach to the gold horse pin. Retail "asking prices" can be higher and vary. Please let me know if you have any additional questions. I’m happy to help. Thank you
