5,248 pennies is a considerable sum of money, coming in at just over 21 pounds. It's quite likely that somewhere, two pence are missing, since 5,250 pence would weigh in very nicely at a round 175 mancuses, which was a commonly used measure during the period. The mancus - from the Arabic manqūsh meaning "struck" - originally referred to a largely ceremonial gold coin based on the weight of an Arab dinar, but rapidly became colloquial for both a weight of gold equivalent to that in a mancus coin, or a sum of thirty pence, the equivalent value in silver.
So what would 175 mancuses get you? Well, conveniently enough, Æthelstan's "Grately II" legal codex of the c.930s establishes a number of prospective base trade values for a series of livestock in an attempt to regulate some elements of trade in England. Very conveniently, Grately II establishes that the base value of a horse is one mancus, so your hoard find would, theoretically at least, allow you to buy 175 generic horses. Of course, you'd probably find at market that you'd be paying far more than one mancus for a good quality horse. Likewise, a base price for cattle is set at 20d, so your 175 mancuses would net you 262 generic cattle, or around 500 sheep, although again you might expect to pay far more for either one based on the quality of the animals and haggling at market.
Land values are far harder to estimate, and there are few baselines to go off. S886, a charter of King Æthelred from 987, establishes that an Ælfswith, wife of thegn Ælfheah, purchased 40 hides of land from King Edgar for a value of 40 mancuses, however in 980, Æthelred sold a hide and half for a gold bracelet (S836) to Winchester Minster for them to build a fishery. "A gold bracelet" is an incredibly vague valuation, but based on the weight of some surviving 9th and 10th century bracelets in the British Museum, the value may have come in at around 2 or 3 Mancuses of gold, or possibly more if the bracelet was inlaid at all. In 926, Æthelstan confirmed by charter two separate purchases made by his thegns of land from the Danes: S396 confirms the purchases of an Ealdred, who bought 5 hides for "10 pounds of silver and gold", while an Uhtred (S397) got a much better deal, securing some 60 hides for '20 pounds of gold and silver'. So your 21 pounds might get you 60 hides, it might get you 21 hides, or it might get you 7-10. Again, like the cattle, this would probably depend quite heavily on the location of the land, its agricultural value, the extent to which it was settled and exploited, its manorial appurtenances etc. A hide of pastoral pasture, for example, might fetch far less value than a few hides of prime agricultural land with a village and mill attached.
