I didn't notice anyone recommending disposal of the LPs as trash or gifting them, but perhaps I have not read the whole thread. In the US, it could work out OK to donate them to a charitable organization and take a tax deduction. I have no idea of the tax laws in Russia. Sure, the OP could go through the collection and keep for himself anything he likes. So far, after X years of storage on his property, it does not appear he has done that. Anything he does now is justified and better from his point of view than what went before. By the way, although I have not discussed the issue with my wife, I plan to suggest to her that she should sell my LPs to a bulk buyer, likely to be a dealer. Or donate them to a charity. She won't need the money, and I cannot imagine her or our sons selling them piecemeal.
