Opinion by

Upon the trial of a scire facias to charge the land in the possession of the heirs of a decedent with a debt for which judgment has been obtained against the administrator, the defendants may make any defense which it would have been competent for them to have made in the original action if they had been parties thereto. The judgment, while conclusive as to the personal estate, as to the real estate is prima facie evidence only, and the plaintiffs’ claim is open to contest on original grounds. This rule is founded on the construction given to section 34 of the act of February 24, 1834, and, while somewhat anomalous, it has been firmly established by the decision in Sergeant’s Heirs v. Ewing, 36 Pa. 156, and the line of cases on which it rests, and it does not seem to have been seriously disputed at the trial.

The defense offered was mainly a denial of liability for the . acceptance by the decedent of bonds instead of money in payment for land which he had sold as agent. This question had been definitively settled in favor of the plaintiffs by the decision of this Court in Paul v. Grimm, reported in 165 Pa. 139, and was no longer open. The right to contest the plaintiffs’ claim notwithstanding the judgment against the administrator was the right to contest it on valid grounds, and all testimony intended to raise again questions which had been decided *333adversely to the defendant was properly excluded. The defendants, however, were denied one ground of defense which it was competent for them to make as affecting the measure of damages. An offer was made to prove that the coal conveyed was not worth $40.00 per acre; that there was no market value for it at the time; that the price was fictitious and much more than the property was worth, and that it was not intended that the sale was for the consideration mentioned in the deed payable in lawful money. The language of the offer is not clear, its purpose was not stated, it was made in connection with other offers of testimony which were properly rejected, and the learned judge in his desire to follow strictly the rulings of this Court doubtless overlooked the effect of the offer and regarded it as part and parcel of the attempt to reopen a question which had been settled. In the interest of justice we should not now give it a too strict construction, and it may fairly be considered as raising the question of the extent of the liability of the agent for exceeding his authority. That question was not passed upon at the first trial and was not considered in the decision in Paul v. Grimm, supra, in which the construction to be given the power of attorney was determined. If the agent sold the land for $40.00 per acre and accepted bonds instead of money in payment, the measure of his liability is the price for which he sold. If, however, it should appear that the price named in the deed was not the real price, but was fictitious ; that the sale was not made, and could not have been made, for that price in money; that the price was in excess of the market value, and was obtained only by reason of the agreement to accept in payment securities of doubtful value, then the recovery against the defendants should be limited to the market value of the land. This would be the measure of the actual loss of the plaintiffs. Their land was sold by an agent with full power to sell and convey, but who without fraud exceeded his authority and accepted bonds instead of money in payment; if they are now paid the full market value of the land at the time, with interest, they are made whole.

We see no other error in the case. It was competent for the defendants to show ratification with knowledge, but there was no sufficient evidence on the subject to justify its submission to the jury. It does not appear from the record of the trial or from *334the argument why the testimony' of ft. C. McCurdy was withdrawn from the jury, and we cannot pass upon the assignment based upon the order striking it out. If offered to show what the real transaction was, it was competent.

The seventh assignment of error is sustained, and the judgment is reversed with a venire facias de novo.
