Try to arrange a time where your husband will come and pick up his belongings. If he is unresponsive to your request, avoid selling his property until you receive permission to do so. Good luck.
Has there been a divorce filing yet and any restraining orders issued that would prevent you from selling the items? If not and you need the funds to run the household or pay the mortgage I'm not seeing a major problem in Ohio with selling the items for a reasonable value. Other jurisdictions such as Arizona and California have community property laws that might affect the result but you appear to be in Ohio. Keep the receipts as you don't want to be accused of dissipating marital property (giving it away or selling it for pennies).
