Reliability of typochronology can be tested by comparing the results of typochronological dating with radiocarbon dating and numismatic dating of coins found in the graves. The radiocarbon measurements were calibrated using the IntCall3 curve and the OxCal 4.2.4. software (Table I) (Reimer et al 2013., Bronk Ramsey 2009.). AMS measurement from human skeletal remains of Grave 34 in Tiszavasvári-Kashalom-dűlő was made in the Poznan Radiocarbon Laboratory in 2010 (Poz-32656 1405±30 BP). Individual calibrated date for grave 34 is between 620 (68.2 %) 657 cal AD and 595 (95.4%) 668 cal AD respectively. The two lightweight solidi minted between 616 and 625 AD were found in the grave (Somogyi 2009. 286-287.). Taking into consideration this numismatic dating, it is possible to refine the results of radiocarbon dating by using Bayesian analysis (Fig. 1) (Buck et al. 1991., Bronk Ramsey 2009.). The probability distribution for grave 34 represents a short time interval between 627 (68.2 %) 655 cal AD and 612 (95.4 %) 663 cal AD (Fig. 2) that confirms the results of typochronological dating (Table II). AMS measurements from human skeletal remains of grave 12 (VERA-4354 1375±30 BP) and grave 19 (VERA-4353 1300±35 BP) in Flajdúnánás-Fürj-halom-járás were made in the Vienna Environmental Research Accelerator (Rácz-Szenthe 2009. 329.). Solidus of Constant II and Constantine IV minted in 662/663 was found in grave 12 (Somogyi 2009. 272-273.). Individual calibrated date for grave 12 is between 640 (68.2%) 670 cal AD and 608 (95.4 %) 684 cal AD. 235
