I read that only the Eastern Orthodox have the Eucharist… not Anglicans…
Holy Orders are preserved when the intent of Holy Orders is preserved. The Anglican communion had a wholesale departure from the intention of the presbytery in the 17th Century, so all of those who were ordained, while they were ordained to Christian ministry, they were not ordained to the sacerdotal ministry that Catholic priests hold.
Later on, the ordination rites changed back, so the intent of having a priest who confers a sacrificial sacrament was present, but bishops who were not ordained as actual bishops cannot ordain actual bishops. However, in the 1930’s, some Anglican bishops, hoping to correct the perceived defect, invited Old Catholic bishops, a post-Vatican I schismatic group, to join in their episcopal ordinations. Hence, there are some Anglican priests and bishops who can legitimately claim succession.
There are also two other Christian churches that have preserved the intent of Holy Orders since their schism from the Catholic Church. These are the Oriental Orthodox Communion, which schismed after the Council of Chalcedon (451) and the Assyrian Church of the East, which schismed after the Council of Ephesus (431).
Finally, there are various small groups of schismatics who have preserved Holy Orders, like the Society of St. Pius X (technically not schismatic, but I would say that full communion is not achieved), the Old Catholics, and a couple others.
There is also disagreement among these groups as to validity. Anglo-Catholics will insist that their Holy Orders are valid, while the Catholics disagree. The Orthodox Church maintains that all sacraments outside of Orthodoxy are defective, and refuses to comment on validity, but some Orthodox do recognize the validity of Catholic sacraments.
It’s a complicated issue. The word validity, while useful, has legalistic and therefore negative connotations. In the Catholic view, whether or not a church has a true Eucharist, that is, whether or not Christ is truly physically present in Body, Blood, Soul and Divinity, is based upon whether or not the intent to have a true Eucharist has been preserved since the church was founded by the apostles.
The Protestant denominations, by embracing consubstantiation or symbolism and denying the sacrificial nature of the Eucharist, have lost the intent of a real Eucharist. This resulted in the loss of a real priesthood. Once lost, you cannot bring priesthood back from nowhere.
So, if you find yourself at a schismatic church, do not hesitate to adore Christ present in the Eucharist. At a Protestant church, there is only bread and wine (or sometimes grape juice).
