Wildwood vineyards cabernet(Sonoma Valley)

[m395711952]

I would like to know if the bottles of this wine are worth anything. They are from the last year Wildwood Vineyards produced a cabernet. They were bought out by Sebastiani Vineyards the next year. The date is either 1978 or 1979. I have them in a safe deposit box and can't remember which year, but it was the last production before the sale of the vineyard. If you could give me any information I would be greatly appreciative.
