1. Sell back to the institution at the time of purchase: If the bank or merchant that originally purchased the gold bars has a repurchase contract or agrees to repurchase, it can repurchase them in the agreed way. This way is usually the most convenient.

2. Selling to gold jewelry stores: Gold bars can be sold to gold jewelry stores, but investors may face disadvantages in terms of discount and depreciation, because gold jewelry stores usually only recycle the gold bars they produce and sell.

3. Sell it to pawnshops or other gold recycling companies: If the original purchasing agency does not recycle it, or the gold jewelry store does not want it, it can choose to sell it to pawnshops or other gold recycling companies. However, this may have more bargaining space, so the price may be lower than that sold to banks and Huangjindian.
